Abstract
Pituitary apoplexy (PA) is a clinical syndrome resulting from a hemorrhagic infarction of the pituitary gland. It is characterized by the sudden onset of visual disturbances, nausea, vomiting, headache and occasionally, signs of meningeal irritation and an altered mental status. The exact pathogenesis of PA remains to be elucidated, although tumor overgrowth of its blood supply remains the most popular theory. Main risk factors for the development of PA include systemic, iatrogenic, and external factors as well as the presence of an underlying pituitary tumor. The diagnostic approach of PA includes both neuroimaging and evaluation of pituitary secretory function. PA is a potentially life-threatening condition which should be managed with hemodynamic stabilization, correction of electrolyte abnormalities and replacement of hormonal deficiencies. PA treatment should be individualized based on the severity of the clinical picture which may vary widely. Treatment options include conservative management with periodic follow-up or neurosurgical intervention, which should be decided by a multidisciplinary team. We conducted a systematic review of the literature to unveil the frequency of PA predisposing factors, clinical and biochemical presentations, management strategies and outcomes.

Pituitary Apoplexy: An Updated Review. J Clin Med 2024; 13:2508. [PMID: 38731037 PMCID: PMC11084238 DOI: 10.3390/jcm13092508] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2024] [Revised: 04/21/2024] [Accepted: 04/23/2024] [Indexed: 05/13/2024] Open
Abstract
Pituitary apoplexy (PA) is an acute, life-threatening clinical syndrome caused by hemorrhage and/or infarction of the pituitary gland. It is clinically characterized by the sudden onset of headache. Depending on the severity, it may also be accompanied by nausea, vomiting, visual disturbances, varying degrees of adenohypophyseal hormone deficiency, and decreased level of consciousness. Corticotropic axis involvement may result in severe hypotension and contribute to impaired level of consciousness. Precipitating factors are present in up to 30% of cases. PA may occur at any age and sometimes develops during pregnancy or the immediate postpartum period. PA occurs more frequently in men aged 50-60, being rare in children and adolescents. It can develop in healthy pituitary glands or those affected by inflammation, infection, or tumor. The main cause of PA is usually spontaneous hemorrhage or infarction of a pituitary adenoma (pituitary neuroendocrine tumor, PitNET). It is a medical emergency requiring immediate attention and, in many cases, urgent surgical intervention and long-term follow-up. Although the majority of patients (70%) require surgery, about one-third can be treated conservatively, mainly by monitoring fluid and electrolyte levels and using intravenous glucocorticoids. There are scoring systems for PA with implications for management and therapeutic outcomes that can help guide therapeutic decisions. Management of PA requires proper evaluation and long-term follow-up by a multidisciplinary team with expertise in pituitary pathology. The aim of the review is to summarize and update the most relevant aspects of the epidemiology, etiopathogenesis, pathophysiology, clinical presentation and clinical forms, diagnosis, therapeutic strategies, and prognosis of PA.

Abstract
Pituitary apoplexy (PA), a rare and life-threatening complication of pituitary adenomas, prompts urgent glucocorticoid administration. The optimal surgical approach is debated, and the Pituitary Apoplexy Score (PAS) aids decision-making. Our retrospective study (2003-2022) assesses variables in PA patient groups (surgical vs. non-surgical), applying PAS to establish a significant threshold for surgical decisions. Additionally, we aim to compare the rates of ophthalmological and endocrine deficit between both groups and identify any associated variables. PAS discrepancies were observed, with averages of 1.7 ± 1.7 (p < 0.0001) for conservative and 3.9 ± 1.7 (p < 0.0001) for surgical groups, confirmed by multivariate analysis (p = 0.009). A PAS threshold of 5, showing over 80% positive predictive value, was established. Patients with low prolactin levels (< 5 ng/ml) had higher corticotropic deficiency prevalence at 3-month and 1-year follow-ups (p = 0.017 and 0.027). Our study supports PAS as a valuable PA management tool, suggesting potential variable adjustments. Multicenter studies are crucial due to PA's low incidence.

A Prospective, Multicenter, Observational Study of Surgical vs Nonsurgical Management for Pituitary Apoplexy. J Clin Endocrinol Metab 2024; 109:e711-e725. [PMID: 37698130 DOI: 10.1210/clinem/dgad541] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Revised: 08/14/2023] [Accepted: 09/08/2023] [Indexed: 09/13/2023]
Abstract
CONTEXT Pituitary apoplexy (PA) has been traditionally considered a neurosurgical emergency, yet retrospective single-institution studies suggest similar outcomes among patients managed medically. OBJECTIVE We established a multicenter, international prospective registry to compare presentation and outcomes in PA patients treated with surgery or medical management alone. METHODS A centralized database captured demographics, comorbidities, clinical presentation, visual findings, hormonal status, and imaging features at admission. Treatment was determined independently by each site. Key outcomes included visual, oculomotor, and hormonal recovery, complications, and hospital length of stay. Outcomes were also compared based on time from symptom onset to surgery, and from admission or transfer to the treating center. Statistical testing compared treatment groups based on 2-sided hypotheses and P less than .05. RESULTS A total of 100 consecutive PA patients from 12 hospitals were enrolled, and 97 (67 surgical and 30 medical) were evaluable. Demographics, clinical features, presenting symptoms, hormonal deficits, and imaging findings were similar between groups. Severe temporal visual field deficit was more common in surgical patients. At 3 and 6 months, hormonal, visual, and oculomotor outcomes were similar. Stratifying based on severity of visual fields demonstrated no difference in any outcome at 3 months. Timing of surgery did not affect outcomes. CONCLUSION We found that medical and surgical management of PA yield similar 3-month outcomes. Although patients undergoing surgery had more severe visual field deficits, we could not clearly demonstrate that surgery led to better outcomes. Even without surgery, apoplectic tumor volumes regress substantially within 2 to 3 months, indicating that surgery is not always needed to reduce mass effect.

Abstract
BACKGROUND Brain stroke is a rare, life-threatening condition associated with pituitary apoplexy (PA), resulting from direct arterial occlusion due to mechanical compression secondary to the sudden enlargement of the pituitary adenoma, or to vessel vasospasm, induced by tumor hemorrhage. CASE REPORT We report the case of a 64-year-old woman with PA complicated by bilateral anterior circulation stroke due to critical stenosis of both anterior cerebral arteries (ACA). Despite the quick surgical decompression and consequent blood flow restoration, the neurological conditions of the patient did not improve and she died 18 days later. Ten other cases of anterior circulation stroke due to PA were retrieved in a systematic review of literature. Clinical and neuroradiological features of these patients and treatment outcome were assessed to suggest the most proper management. CONCLUSION The onset of neurological symptoms suggestive for brain stroke in patients with PA requires performing an emergency Magnetic Resonance Imaging (MRI), including Diffusion-weighted and angiographic MR-sequences. The role of surgery in these cases is debated, however, transsphenoidal adenomectomy would permit us to decompress the ACA and restore blood flow in their territories. Although the prognosis of PA-induced anterior circulation stroke is generally poor, a timely diagnosis and treatment would be paramount for improving patient outcome.

Update on Current Evidence for the Diagnosis and Management of Nonfunctioning Pituitary Neuroendocrine Tumors. Endocrinol Metab (Seoul) 2023; 38:631-654. [PMID: 37964483 PMCID: PMC10764990 DOI: 10.3803/enm.2023.1838] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 10/29/2023] [Accepted: 11/01/2023] [Indexed: 11/16/2023] Open
Abstract
Pituitary neuroendocrine tumors (PitNETs) are the third most frequently diagnosed intracranial tumors, with nonfunctioning PitNETs (nfPitNETs) accounting for 30% of all pituitary tumors and representing the most common type of macroPitNETs. NfPitNETs are usually benign tumors with no evidence of hormone oversecretion except for hyperprolactinemia secondary to pituitary stalk compression. Due to this, they do not typically present with clinical syndromes like acromegaly, Cushing's disease or hyperthyroidism and instead are identified incidentally on imaging or from symptoms of mass effects (headache, vision changes, apoplexy). With the lack of effective medical interventions, first-line treatment is transsphenoidal surgical resection, however, nfPitNETs often have supra- or parasellar extension, and total resection of the tumor is often not possible, resulting in residual tumor regrowth or reoccurrence. While functional PitNETs can be easily followed for recurrence using hormonal biomarkers, there is no similar parameter to predict recurrence in nfPitNETs, hence delaying early recognition and timely management. Therefore, there is a need to identify prognostic biomarkers that can be used for patient surveillance and as therapeutic targets. This review focuses on summarizing the current evidence on nfPitNETs, with a special focus on potential new biomarkers and therapeutics.

Abstract
BACKGROUND Conjunctival chemosis (CC) is an extremely rare symptom of pituitary neuroendocrine tumor (PitNET). We report an extremely rare case of PitNET manifesting as severe CC. CASE PRESENTATION A 48-year-old male was admitted to our hospital with severe CC, proptosis, and ptosis of the right eye. Magnetic resonance imaging demonstrated the tumor mass invading the cavernous sinus (CS) with cystic lesion. The patient underwent emergent endoscopic transsphenoidal surgery, and the pathological diagnosis was PitNET. CC of the right eye remarkably improved after the surgery. Glucocorticoid therapy was performed for right oculomotor nerve palsy, which rapidly improved. The postoperative course was uneventful and the patient was discharged from our hospital without hormone replacement. CONCLUSIONS CC caused by CS invasion of PitNET can be cured by early surgical treatment. Therefore, PitNET is important to consider in the differential diagnosis of CC.

Abstract
OBJECTIVE This study aimed to clarify the symptoms of pituitary or parasellar tumor onset with cranial nerve palsy (CNP) and to improve our knowledge of this rare symptom and its most appropriate treatment. METHODS Among 1281 patients with pituitary or parasellar tumors surgically treated from 2003 to 2020, 30 cases (2.34%; 15 men and 15 women; mean age: 55.6 years, range: 6-83 years) first presenting with CNP were reviewed to evaluate the neurological symptoms, histological diagnosis, interval from onset to surgery, and time before complete CNP recovery. RESULTS Pathological diagnoses comprised 17 pituitary adenomas, including 10 pituitary apoplexies and 4 adrenocorticotropic hormone-positive adenomas, and 13 other tumors, including 3 chordomas, 2 xanthogranulomas, 2 malignant lymphomas, 2 metastatic tumors, 1 Rathke cleft cyst, 1 plasmacytoma, 1 craniopharyngioma, and 1 neuroendocrine carcinoma. The mechanisms causing CNP were pituitary apoplexy (n = 10), cranial nerve compression or involvement (n = 17), and inflammatory changes (n = 9). As the first manifestation, 20 (66.7%) patients presented with oculomotor nerve palsy, 2 (6.7%) with trochlear nerve palsy, and 13 (43.3%) with abducens nerve palsy. Full recovery of CNP was obtained in 25 patients (83.3%) after surgery alone and in 2 patients (6.7%) after adjuvant therapy. Early surgery provided no significant difference in full recovery rates although it reduced the time to reach full recovery. CONCLUSIONS It is critical to determine the mechanisms of CNP and intervene surgically to improve symptoms, shorten the duration of the disorder, prevent relapses, and obtain the correct pathological diagnosis to select the proper adjuvant therapy.

Abstract
BACKGROUND AND AIMS Pituitary apoplexy (PA) is a rare neurosurgical emergency, associated with deficiency of one or more pituitary hormones. Few studies have explored the relative outcomes associated with conservative and neurosurgical intervention. METHODS A retrospective evaluation of all patients with PA reviewed at Morriston Hospital was undertaken and diagnosis was obtained from Morriston database (Leicester Clinical Workstation database) between 1998 and 2019 from clinic letters and discharge summaries. RESULTS Thirty-nine patients with PA were identified with a mean age of 74.5 years and 20 (51.3%) patients were women. Patients were followed up for a mean±SD 68.1±61.7 months. Twenty-three (59.0%) patients had a known pituitary adenoma. Commoner clinical presentations of PA were ophthalmoplegia or visual field loss. Following PA, 34 (87.2%) patients were noted to have a non-functioning pituitary adenoma (either pre-existing or new), while 5 (12.8%) patients had a pre-existing functional macroadenoma. Neurosurgical intervention was taken in 15 (38.5%) patients of which 3 (20.0%) patients also received radiotherapy, 2 (13.3%) patients had radiotherapy alone and the remainder managed conservatively. External ophthalmoplegia recovered in all cases. Visual loss remained in all cases. One (2.6%) patient with chromophobe adenoma had a significant second episode of PA requiring repeat surgery. CONCLUSION PA often occurs in patients with undiagnosed adenoma. Hypopituitarism commonly occurred following conservative or surgical treatment. External ophthalmoplegia resolved in all cases, however, visual loss did not recover. Pituitary tumour recurrence and further PA episodes are rare.

Abstract
PURPOSE To compare the clinical, hormonal, and radiological presentation and surgical outcomes of patients with macroadenomas presenting with pituitary apoplexy and patients not presenting pituitary apoplexy. METHODS Multicentre retrospective study of patients presenting with macroadenomas and pituitary apoplexy in three Spanish tertiary hospitals between 2008 and 2022. We selected as control group (non-pituitary apoplexy), patients with pituitary macroadenomas without apoplexy who underwent pituitary surgery between 2008 and 2020. RESULTS A total of 60 patients with apoplexy and 185 without apoplexy were enrolled. Patients with pituitary apoplexy were more frequently men (70% vs. 48.1%, p = 0.003), had higher prevalence of hypertension (43.3% vs. 26.0%, p = 0.011) and of obesity (23.3% vs. 9.7%, P = 0.007), were under treatment with anticoagulants more commonly (11.7% vs. 4.3%, P = 0.039) and had larger (27.5 ± 11.03 vs. 23.6 ± 12.55 mm, p = 0.035) and invasive pituitary macroadenomas more frequently (85.7% vs. 44.3%, P < 0.001) than those without apoplexy. Surgical remission was more frequent in patients with pituitary apoplexy than those without apoplexy (OR 4.55, P < 0.001), but they developed new pituitary deficits (OR 13.29, P < 0.001) and permanent diabetes insipidus (OR 3.40, P = 0.022) more commonly. However, visual improvement (OR 6.52, p < 0.001) and complete pituitary function recovery (OR 2.37, P < 0.001) was more common in patients without apoplexy. CONCLUSION Surgical resection is more common in patients presenting with pituitary apoplexy than those without apoplexy; however, visual improvement and complete recovery of pituitary function is more common in patients without apoplexy. The risk of new pituitary deficits and permanent diabetes insipidus is higher in patients with apoplexy than in those without it.

Pituitary Apoplexy in Patients with Pituitary Neuroendocrine Tumors (PitNET). Biomedicines 2023; 11:biomedicines11030680. [PMID: 36979658 PMCID: PMC10044830 DOI: 10.3390/biomedicines11030680] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2023] [Revised: 02/17/2023] [Accepted: 02/21/2023] [Indexed: 02/26/2023] Open
Abstract
Various complications of pituitary neuroendocrine tumors (PitNET) are reported, and an intratumor hemorrhage or infarct underlying pituitary apoplexy (PA) represents an uncommon, yet potentially life-threatening, feature, and thus early recognition and prompt intervention are important. Our purpose is to overview PA from clinical presentation to management and outcome. This is a narrative review of the English-language, PubMed-based original articles from 2012 to 2022 concerning PA, with the exception of pregnancy- and COVID-19-associated PA, and non-spontaneous PA (prior specific therapy for PitNET). We identified 194 original papers including 1452 patients with PA (926 males, 525 females, and one transgender male; a male-to-female ratio of 1.76; mean age at PA diagnostic of 50.52 years, the youngest being 9, the oldest being 85). Clinical presentation included severe headache in the majority of cases (but some exceptions are registered, as well); neuro-ophthalmic panel with nausea and vomiting, meningism, and cerebral ischemia; respectively, decreased visual acuity to complete blindness in two cases; visual field defects: hemianopia, cranial nerve palsies manifesting as diplopia in the majority, followed by ptosis and ophthalmoplegia (most frequent cranial nerve affected was the oculomotor nerve, and, rarely, abducens and trochlear); proptosis (N = 2 cases). Risk factors are high blood pressure followed by diabetes mellitus as the main elements. Qualitative analysis also pointed out infections, trauma, hematologic conditions (thrombocytopenia, polycythemia), Takotsubo cardiomyopathy, and T3 thyrotoxicosis. Iatrogenic elements may be classified into three main categories: medication, diagnostic tests and techniques, and surgical procedures. The first group is dominated by anticoagulant and antiplatelet drugs; additionally, at a low level of statistical evidence, we mention androgen deprivation therapy for prostate cancer, chemotherapy, thyroxine therapy, oral contraceptives, and phosphodiesterase 5 inhibitors. The second category includes a dexamethasone suppression test, clomiphene use, combined endocrine stimulation tests, and a regadenoson myocardial perfusion scan. The third category involves major surgery, laparoscopic surgery, coronary artery bypass surgery, mitral valvuloplasty, endonasal surgery, and lumbar fusion surgery in a prone position. PA in PitNETs still represents a challenging condition requiring a multidisciplinary team from first presentation to short- and long-term management. Controversies involve the specific panel of risk factors and adequate protocols with concern to neurosurgical decisions and their timing versus conservative approach. The present decade-based analysis, to our knowledge the largest so far on published cases, confirms a lack of unanimous approach and criteria of intervention, a large panel of circumstantial events, and potential triggers with different levels of statistical significance, in addition to a heterogeneous clinical picture (if any, as seen in subacute PA) and a spectrum of evolution that varies from spontaneous remission and control of PitNET-associated hormonal excess to exitus. Awareness is mandatory. A total of 25 cohorts have been published so far with more than 10 PA cases/studies, whereas the largest cohorts enrolled around 100 patients. Further studies are necessary.

Abstract
Background:
Patients diagnosed with pituitary apoplexy and presenting with acute visual deterioration require urgent surgical resection. This is also commonly associated with pituitary hypopituitarism that requires hormonal replacement for correction. This study was undertaken to evaluate the clinical recovery of 45 patients diagnosed with symptomatic pituitary apoplexy who underwent early (within 72 h of symptom onset) endoscopic transsphenoidal surgical resection with an emphasis on visual, ocular craniopathy, and endocrinological outcome.
Methods:
This is a retrospective analysis of a consecutive series of patients diagnosed with pituitary apoplexy between 2011 and 2020 treated by early (within 72 h of symptom onset) endoscopic transsphenoidal surgical resection. All tumors were histologically proven as pituitary adenomas. Clinical and neuro-ophthalmological examinations, imaging studies, and endocrinological evaluation were retrospectively reviewed. Patients with a minimum of 6 months follow-up were included in the study. The influence of patients’ demographics, extent of visual and ocular motility impairment, preoperative endocrinological dysfunction, tumor size and extent, degree of resection, and surgical complications were analyzed as potential prognostic factors for recovery.
Results:
Forty-five patients were included in this retrospective study. Ages ranged from 27 to 57 years (mean: 42 years). All patients presented with headache and variable degrees of visual loss and visual field deficit. Ophthalmoplegia was present in 22 (48.9%) patients with 17 (37.8%) having bilateral ocular cranial nerve palsy. All patients had variable degrees of endocrinological deficiencies. All patients showed evidence of low cortisol, 14 (31.1%) showed hypothyroidism and 11 (24.4%) showed hypogonadism. There was evidence of hyperprolactinemia in 16 (35.6%) patients. All patients harbored a pituitary macroadenoma. Tumor resection was complete in 33 (73%) of patients, with residual tumor related to cavernous sinus or retrosellar extension. Operative complications were mainly related to short-term nasal complications occurring in 14 (31%) patients. Cerebrospinal fluid leak requiring revision surgery occurred in only one patient harboring a modified SIPAP Grade 3s tumor. Transient diabetes insipidus occurred in 9 (20%) patients, with 2 (4.4%) requiring long-term hormonal replacement. The mean follow-up was 25 months. Baseline visual improvement was achieved in 39 (86.7%) patients. Ocular cranial nerve palsy showed complete recovery in 17 (77.2%) patients. Endocrine follow-up showed that patients with panhypopituitarism (11 [24.4%]) failed to recover.
Conclusion:
The current surgical series showed safety in terms of low complication rate and efficacy in terms of clinical outcome. The significant prognostic factor related to visual recovery was the degree of preoperative visual deficit. Recovery of ocular cranial neuropathy showed a higher recovery rate when it was unilateral as opposed to bilateral. Pituitary hormonal recovery was less favorable with pituitary panhypopituitarism being a poor prognostic factor.

Abstract
Background Pituitary apoplexy is a rare endocrine emergency, which commonly presents with headache and is occasionally associated with visual disturbances. Prompt diagnosis and treatment can be both life and vision saving. In the emergence of novel coronavirus and global pandemic, rapid development of new vaccines have shown to reduce morbidity and mortality associated with Covid-19. Recognition of rare potential adverse effects of these vaccines including pituitary apoplexy are yet to be reported. A causal link between pituitary apoplexy and COVID-19 vaccination has not been established. Case presentation We report a case of a 24-year-old woman who presented with progressively worsening headache soon after completing her COVID-19 vaccination. Imaging showed pituitary apoplexy with an underlying pituitary mass. In view of the age and the typical presentation of severe headache, pituitary hypophysitis was considered, despite the absence of the almost pathognomonic feature of a thickened pituitary stalk in the initial imaging. In the context that the headache had started shortly after the administration of the second dose of COVID-19 vaccine, this potentially could have been the trigger for the occurrence of pituitary apoplexy. Conclusion Although the pathophysiology is not entirely clear and no direct link could be ascertained, our patient may have developed an exaggerated immunological response after the vaccine, with a possible pituitary hypophysitis leading to a pituitary apoplexy.

Pituitary apoplexy (PA) is a rare clinical syndrome due to pituitary hemorrhage or infarction. It is characterized by the sudden onset of one or more of the following: severe headache, visual disturbance, nausea/vomiting, and or altered mental status. Most commonly, PA occurs in an underlying pituitary adenoma. The pathophysiology is not fully understood, but it is thought to involve elements of increased metabolic demand and/or compromise to the vasculature of the pituitary or pituitary tumor. Several risk factors have been described. Stabilization of the patient on presentation, replacement of hormonal deficiencies, and reversal of electrolyte abnormalities are the recommended initial steps in the management of patients with PA. Surgical decompression of the mass effect had been the recommended treatment for patients with PA; however, retrospective studies of patients with PA have demonstrated similar outcomes when a conservative approach is applied. This suggests that in highly selected clinical scenarios (mild visual deficit and improving symptoms), conservative management is possible. Further studies, however, are necessary to better stratify patients but are limited by the rarity of the condition and the acuity.

Surgery for Pituitary Tumor Apoplexy Is Associated with Rapid Headache and Cranial Nerve Improvement. Curr Oncol 2022; 29:4914-4922. [PMID: 35877250 PMCID: PMC9319222 DOI: 10.3390/curroncol29070390] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Revised: 07/06/2022] [Accepted: 07/07/2022] [Indexed: 11/17/2022] Open
Abstract
Pituitary tumor apoplexy (PTA) classically comprises sudden-onset headache, loss of vision, ophthalmoparesis, and decreased consciousness. It typically results from hemorrhage and/or infarction within a pituitary adenoma. Presentation is heterologous, and optimal management is debated. The time course of recovery of cranial nerve deficits (CNDs) and headaches is not well established. In this study, a retrospective series of consecutive patients with PTA managed at a single academic institution over a 22-year period is presented. Headaches at the time of surgery were more severe in the early and subacute surgical cohort and improved significantly within 72 h postoperatively (p < 0.01). At one year, 90% of CNDs affecting cranial nerves (CNs) 3, 4, and 6 had recovered, with no differences between early (<4 d), subacute (4−14 d), and delayed (>14 d) time-to-surgery cohorts. Remarkably, half recovered within three days. In total, 56% of CN2 deficits recovered, with the early surgery cohort including more severe deficits and recovering at a lower rate (p = 0.01). No correlation of time-to-surgery and rapidity of recovery of CNDs was observed (p = 0.65, 0.72). Surgery for PTA is associated with rapid recovery of CNDs in the early, subacute, and delayed time frames, and with rapid headache improvement in the early and subacute time frames in 50% or more of patients.

Abstract
Summary Pituitary apoplexy (PA) is a medical emergency with complex diagnosis and management. In this study, we describe a case of PA in a 63-year-old male treated with oral anticoagulant therapy for atrial fibrillation. In the patient, PA manifested itself with asthenia and severe headache not responsive to common analgesics. Despite the finding of a pituitary mass through CT, and in anticipation of the endocrinological evaluation and pituitary MRI, the patient's clinical condition worsened with an escalation of headache and asthenia associated with deterioration of the visual field and impairment of consciousness level. The emergency assessments revealed an adrenal failure, whereas MRI showed a haemorrhagic pituitary macroadenoma with compression of the optic chiasm. Intravenous fluids repletion and high-dose hydrocortisone were started with a rapid improvement of the patient's health and visual field abnormalities. Hydrocortisone was gradually reduced to a replacement dose. During the follow-up, panhypopituitarism was documented, and replacement therapies with l-thyroxine and testosterone were introduced. Three months later, a pituitary MRI showed a 50% reduction in the pituitary adenoma volume. Learning points Pituitary apoplexy (PA) is a medical emergency that can result in haemodynamic instability and abnormalities in the level of consciousness. The management of PA requires a multidisciplinary team that includes endocrinologists, ophthalmologists, neuro-radiologists, and neuro-surgeons. Pituitary MRI with gadolinium is the diagnostic gold standard for PA. PA therapy aims to improve general conditions and treat compression symptoms, especially visual field abnormalities. Adrenocorticotrophic hormone deficiency is a common and severe complication of PA. Thus, all patients with PA must be promptly treated with injective synthetic glucocorticoids (e.g. hydrocortisone 100 mg) and i.v. saline. PA must be taken into consideration in case of sudden headache in patients with a pituitary macroadenoma, especially if other risk factors are recognized.

Abstract
In human medicine, pituitary apoplexy (PA) is a clinical syndrome characterised by the sudden onset of neurological signs because of haemorrhage or infarction occurring within a normal or tumoral pituitary gland. The diagnosis is usually performed combining neurological signs and imaging findings. The aim of the present study is to describe the abnormal neurological signs, the diagnostic imaging findings, based on Computed Tomography (CT) and/or Magnetic Resonance Imaging (MRI), and the outcome in a population of dogs with suspected PA. Clinical cases were retrospectively reviewed. Nineteen cases of suspected PA were included. The majority of dogs showed behavioural abnormalities (11/19). Neurological signs more frequently identified were obtundation (7/19), vestibular signs (7/19) and epileptic seizures (6/19). The onset of neurological signs was per-acute in 14 out of 19 cases. Data regarding CT and MRI were available in 18 and 9 cases, respectively. Neurological signs resolved in less than 24 h in seven patients. The short-term prognosis was defined as favourable in the majority of our study population. The median survival time was of 7 months from the time of PA diagnosis. This is the first description of neurological signs, imaging findings and outcome in a large group of dogs with PA.

Abstract
INTRODUCTION Depending on severity of presentation, pituitary apoplexy can be managed with acute surgery or non-operatively. We aim to assess long-term tumour control, visual and endocrinological outcomes following pituitary apoplexy with special emphasis on patients treated non-operatively. METHODS Multicentre retrospective cohort study. All patients with symptomatic pituitary apoplexy were included. Patients were divided into 3 groups: group 1: surgery within 7 days; group 2: surgery 7 days-3 months; group 3: non-operative. Further intervention for oncological reasons during follow-up was the primary outcome. Secondary outcome measures included visual and endocrinological function at last follow-up. RESULTS One hundred sixty patients were identified with mean follow-up of 48 months (n = 61 group 1; n = 34 group 2; n = 64 group 3). Factors influencing decision for surgical treatment included visual acuity loss (OR: 2.50; 95% CI: 1.02-6.10), oculomotor nerve palsy (OR: 2.80; 95% CI: 1.08-7.25) and compression of chiasm on imaging (OR: 9.50; 95% CI: 2.06-43.73). Treatment for tumour progression/recurrence was required in 17%, 37% and 24% in groups 1, 2 and 3, respectively (p = 0.07). Urgent surgery (OR: 0.16; 95% CI: 0.04-0.59) and tumour regression on follow-up (OR: 0.04; 95% CI: 0.04-0.36) were independently associated with long-term tumour control. Visual and endocrinological outcomes were comparable between groups. CONCLUSION Urgent surgery is an independent predictor of long-term tumour control following pituitary apoplexy. However, 76% of patients who successfully complete 3 months of non-operative treatment may not require any intervention in the long term.

Abstract
ObjectiveIschemic infarction of pituitary apoplexy (PA) is a rare type of pituitary apoplexy. This study aims to characterize ischemic PA via clinical presentations, imaging data, histopathological manifestations, and focus on the management and prognosis of the disease.MethodsThis study retrospectively identified 46 patients with ischemic PA confirmed using histopathology at a single institution from January 2013 to December 2020. The clinical presentations, imaging data, laboratory examination, management, and outcomes were collected. We then summarized the clinical presentations, imaging features, intraoperative findings, and histopathological manifestations, and compared the outcomes based on the timing of surgical intervention.ResultsHeadache was the most common initial symptom (95.65%, 44/46), followed by visual disturbance (89.13%, 41/46), and nausea and vomiting (58.70%, 27/46). 91.3% of the patients had at least one pituitary dysfunction, with hypogonadism being the most common endocrine dysfunction (84.78%, 39/46). Cortisol dysfunction occurred in 24 (52.17%) patients and thyroid dysfunction occurred in 17 (36.96%). Typical rim enhancement and thickening of the sphenoid sinus on MRI were seen in 35 (85.37%) and 26 (56.52%) patients, respectively. Except for one patient with asymptomatic apoplexy, the remaining patients underwent early (≤ 1 week, 12 patients) and delayed (> 1 week, 33 patients) transsphenoidal surgery. Total tumor resection was achieved in 27 patients and subtotal tumor resection in 19 patients. At surgery, cottage cheese–like necrosis was observed in 50% (23/46) of the patients. At the last follow-up of 5.5 ± 2.7 years, 92.68% (38/41) of the patients had gained a significant improvement in visual disturbance regardless of surgical timing, and 65% of the patients were still receiving long-term hormone replacement therapy.ConclusionPatients with ischemic PA can be accurately diagnosed by typical imaging characteristics preoperatively. The timing of surgical intervention does not significantly affect the resolution of neurological and endocrinological dysfunctions. Preoperative endocrine dysfunctions are common and usually appear to be poor after surgical intervention.

Abstract
Pituitary apoplexy (PA) is a rare clinical syndrome related to abrupt hemorrhage and/or infarction of the pituitary gland, usually occurring in patients with preexisting pituitary disease. It is an endocrine emergency requiring rapid diagnosis and appropriate management. This is a literature review and a retrospective study reporting the observation of four patients that have suffered from pituitary macroadenomas. These observations illustrate the particularities of this pathology in the elderly. The symptoms may be truncated and lead to a late diagnosis with its repercussions on management, without forgetting the particularity of the fragile and multisystemic terrain, which may contraindicate the usual surgical treatment. A rapid diagnosis and appropriate management can limit the occurrence of irreversible complications.

Abstract
Coordination of care for patients with neuro-ophthalmic disorders can be very challenging in the community emergency department (ED) setting. Unlike university- or tertiary hospital-based EDs, the general ophthalmologist is often not as familiar with neuro-ophthalmology and the examination of neuro-ophthalmology patients in the acute ED setting. Embracing image capturing of the fundus, using a non-mydriatic camera, may be a game-changer for communication between ED physicians, ophthalmologists, and tele-neurologists. Patient care decisions can now be made with photographic documentation that is then conveyed through HIPAA-compliant messaging with accurate and useful information with both ease and convenience. Likewise, external photos of the anterior segment and motility are also helpful. Finally, establishing clinical and imaging guidelines for common neuro-ophthalmic disorders can help facilitate complete and appropriate evaluation and treatment.

Factors predicting neuro-endocrine recovery following transsphenoidal surgery in pituitary apoplexy patients. World Neurosurg 2021; 159:e40-e47.

Abstract
BACKGROUND Pituitary apoplexy is a rare clinical syndrome. Only a few studies have examined factors associated with recovery of neuro-endocrine functions following transsphenoidal surgery. This study aimed to identify factors associated with neuro-endocrine recovery following surgery for pituitary apoplexy. METHODS The records of pituitary apoplexy patients who underwent transsphenoidal surgery at Songklanagarind Hospital between January 2005 and December 2020 were retrospectively reviewed. The primary outcomes were the recoveries of preoperative visual acuity (VA), visual field (VF), cranial nerve function, and pituitary hormone deficits. Using logistic regression analysis, various factors were analyzed for their associations with recovery of neuro-endocrine functions. RESULTS The study included 98 patients. Multivariate analysis showed that older age and greater suprasellar extension were associated with no recovery of VA (P = 0.042 and P = 0.018, respectively). Only 33% of patients aged > 55 years and suprasellar extension of lesion ≥ 25 mm gained recovery of VA, while 100% of patients with neither of these factors had recovery. Underlying hypertension was associated with no recovery of preoperative VF defect (P = 0.027). Wilson-Hardy classification-invasion grades 3-4 and lower preoperative serum prolactin level were associated with no recovery from preoperative hypoadrenalism and hypothyroidism (P = 0.016 and P = 0.007, respectively). CONCLUSIONS Older age, higher suprasellar extension, and hypertension were poor prognostic factors for visual recovery. Wilson-Hardy inferior invasion grade 3-4 and lower preoperative serum prolactin level were poor prognostic factors for recovery from hypopituitarism. Stratifying patients according to these prognostic factors may assist in selecting patients for surgery.

Abstract
Background: Rathke cleft cyst (RCC) apoplexy is an uncommon type of lesion that is challenging to diagnose without histopathological samples. Very few articles have been published describing the details of RCC apoplexy. We studied a good number of published articles to analyze its demographics, clinical and hormonal presentations, and outcomes. Methods: A literature review of English language publications about RCC apoplexy or pituitary apoplexy was conducted using Medline and EMBASE search engines. Thirty articles with histological diagnosis of RCC apoplexy were identified, the earliest of which was published in 1990 and the latest in 2019. We combined the findings of these articles with our own case report and then compared the demographics, clinical and hormonal presentations, and outcomes between RCC apoplexy and pituitary adenoma apoplexy. Results: Our data included 29 patients with RCC, with a mean age of 36.87 years (8–72) and a predominance of female patients (68%). The hemorrhagic type was most common, reported in 86%. Headache was the most common presenting symptom, being reported in 93% followed by hypogonadism (73%) and hormonal deficits (52%). All but three patients improved neurologically (90%); however, 45% of patients required long-term hormonal replacement, mostly thyroid hormone. No cases of worsening neurological or hormonal status were reported. Conclusion: RCC apoplexy presents with less severe neurological and hormonal abnormalities than pituitary adenoma apoplexy; it also has a better prognosis in endocrine functional recovery. We recommend applying current management guidelines of pituitary adenoma apoplexy to RCC apoplexy.

Abstract
Purpose: This study investigated the clinical manifestations, surgical method, and treatment outcomes of patients with pituitary apoplexy and evaluated the safety and effectiveness of the endoscopic endonasal transsphenoidal approach in the treatment of pituitary adenomas. Patients and methods: In this retrospective study, were analyzed the data of patients with symptomatic pituitary apoplexy who received surgical treatment by endoscopic endonasal transsphenoidal approach from January 2017 to June 2020 at the Department of Neurosurgery of the First Affiliated Hospital of Bengbu Medical College. Patients were followed up through outpatient visits and telephone interviews. Results: Data for 24 patients including 13 males and 11 females with an average age of 46.46 years were analyzed. Headache (83.33%) and visual disturbances (75.00%) were the most common preoperative manifestations. In the 24 patients, 21 (87.50%) tumors were completely removed and 3 (12.50%) were partly removed. Intractable headache improved in all patients over a mean follow-up time of 25.16 months, and postoperative improvement in visual acuity was achieved in 17 of 18 patients (94.44%) with vision defects. Four patients (16.67%) experienced transient urinary collapse after the operation. No intracranial infection, carotid artery injury, or death occurred. Conclusion: The endoscopic endonasal transsphenoidal approach is a safe and effective method for the treatment of pituitary apoplexy.

Abstract
OBJECTIVES To report a case of isolated third nerve palsy from pituitary apoplexy and perform a systematic literature review. MATERIALS AND METHODS MEDLINE/EMBASE databases were searched up to September 2020. INCLUSION CRITERIA Age≥18, isolated third nerve palsy from pituitary apoplexy. EXCLUSION CRITERIA Age<18, presence of other neurological findings, no hemorrhage or infarction of pituitary. RESULTS Case report: A 76-year-old woman presented with headache and right-sided ptosis. Right-eye exam revealed complete ptosis, absent pupillary constriction and accommodation, depressed and abducted eye on primary gaze, and -1 impaired depression, adduction, elevation, without other neurological findings. Brain MRI was suggestive of pituitary apoplexy. Pathology after transsphenoidal resection revealed an infarcted pituitary adenoma. Third nerve palsy resolved completely in 21 days. Systematic review: Twenty-three studies reporting 35 patients were selected from 182 abstracts. Twenty-nine (83%) had complete isolated third nerve palsy. Headache was reported in 31 (97%). Thirty-one had hemorrhage and 1 had infarction of pituitary. Cavernous sinus invasion occurred in 14 (50%). Twenty-eight were managed surgically (80%) and 7 medically (20%). Nerve palsy resolved completely in 27 (82%) and partially in 4 (11%). CONCLUSIONS Pituitary apoplexy is an important differential diagnosis in patients with isolated third nerve palsy. Isolated third nerve palsy in apoplexy appears to have favorable prognosis.

Abstract
OBJECTIVE Early surgical intervention for patients with pituitary apoplexy (PA) is thought to improve visual outcomes and decrease mortality. However, some patients may have good clinical outcomes without surgery. The authors sought to compare the radiological and clinical outcomes of patients with PA who were managed conservatively versus those who underwent early surgery. METHODS Patients with symptomatic PA were identified. Radiological, endocrinological, and ophthalmological data were reviewed. Patients with progressive visual deterioration or ophthalmoplegia were candidates for early surgery (within 7 days). Patients without visual symptoms or whose symptoms improved on high-dose steroids were treated conservatively. Log-rank and univariate analysis compared clinical and radiological outcomes between those receiving early surgery and those who underwent intended conservative management. RESULTS Sixty-four patients with PA were identified: 47 (73.4%) underwent intended conservative management, while 17 (26.6%) had early surgery. Patients receiving early surgery had increased rates of impaired visual acuity (VA; 64.7% vs 27.7%, p = 0.009); visual field (VF) deficits (64.7% vs 19.2%, p = 0.002); and cranial neuropathies (58.8% vs 29.8%, p < 0.05) at presentation. Tumor volumes were greater in the early surgical cohort (15.1 ± 14.8 cm3 vs 4.5 ± 10.3 cm3, p < 0.001). The median clinical and radiological follow-up visits were longer in the early surgical cohort (70.0 and 64.4 months vs 26.0 and 24.7 months, respectively; p < 0.001). Among those with VA/VF deficits, visual outcomes were similar between both groups (p > 0.9). The median time to VA improvement (2.0 vs 3.0 months, p = 0.9; HR 0.9, 95% CI 0.3-3.5) and the median time to VF improvement (2.0 vs 1.5 months; HR 0.8, 95% CI 0.3-2.6, p = 0.8) were similar across both cohorts. Cranial neuropathy improvement was more common in conservatively managed patients (HR 4.8, 95% CI 1.5-15.4, p < 0.01). Conservative management failed in 7 patients (14.9%) and required surgery. PA volumes spontaneously regressed in 95.0% of patients (38/40) with successful conservative management, with a 6-month regression rate of 66.2%. Twenty-seven patients (19 in the conservative and 8 in the early surgical cohorts) responded to a prospectively administered Visual Function Questionnaire-25 (VFQ-25). VFQ-25 scores were similar across both cohorts (conservative 95.5 ± 3.8, surgery 93.2 ± 5.1, p = 0.3). Younger age, female sex, and patients with VF deficits or chiasmal compression were more likely to experience unsuccessful conservative management. Surgical outcomes were similar for patients receiving early versus delayed surgery. CONCLUSIONS These data suggest that a majority of patients with PA can be successfully managed without surgical intervention assuming close neurosurgical, radiological, and ophthalmological follow-up is available.

Comparative analysis of pituitary adenoma with and without apoplexy in pediatric and adolescent patients: a clinical series of 80 patients. Neurosurg Rev 2021; 45:491-498.

Abstract
Pituitary adenomas (PAs) have a low incidence in pediatric and adolescent patients, and their clinical characteristics remain unclear. As a severe complication of PA, apoplexy was investigated in young patients in the present study. Eighty patients younger than 20 years with PAs who underwent surgery were included and divided into an apoplexy group and non-apoplexy group. The clinical data of these two groups were statistically analyzed and compared. The study included 33 boys and 47 girls, with a mean age of 16.9 years. There were six (7.5%) adrenocorticotropic hormone-secreting, 13 (16.3%) growth hormone-secreting, 47 (58.7%) prolactin-secreting, and 14 (17.5%) non-functioning PAs. There were 34 (42.5%) patients in the apoplexy group and 46 (57.5%) patients in the non-apoplexy group. Pre-operatively, patients in the apoplexy group were more likely to have visual impairment (hazard ratio: 2.841, 95% confidence interval: 1.073-7.519; P = 0.033) and had poorer visual impairment scores than those in the non-apoplexy group (P = 0.027). Furthermore, a longer duration of symptoms before surgery was significantly correlated with a poorer visual outcome in the apoplexy group (R = - 1.204; P = 0.035). However, apoplexy was not associated with tumor type, tumor size, resection rate, or tumor recurrence. Tumor apoplexy is common in pediatric and adolescent patients with PAs and is associated with more severe preoperative visual deficits. Hence, the appropriate timing of surgical treatment may be important for rescuing visual function in young PA patients.

Abstract
Objective To analyze the clinical, laboratory, and radiological findings and management of patients with clinical pituitary apoplexy and to screen for aryl hydrocarbon receptor-interacting protein (AIP) mutations. Methods The clinical findings were collected from the medical records of consecutive sporadic pituitary adenoma patients with clinical apoplexy. Possible precipitating factors, laboratory data, magnetic resonance imaging (MRI) findings and treatment were also analyzed. Peripheral blood samples were obtained for DNA extraction from leukocytes, and the entire AIP coding region was sequenced. Results Thirty-five patients with pituitary adenoma were included, and 23 (67%) had non-functioning pituitary adenomas. Headache was observed in 31 (89%) patients. No clear precipitating factor was identified. Hypopituitarism was observed in 14 (40%) patients. MRI from 20 patients was analyzed, and 10 (50%) maintained a hyperintense signal in MRI performed more than three weeks after pituitary apoplexy (PA). Surgery was performed in ten (28%) patients, and 25 (72%) were treated conservatively with good outcomes. No AIP mutation was found in this cohort. Conclusion Patients with stable neuroophthalmological impairments can be treated conservatively if no significant visual loss is present. Our radiological findings suggest that hematoma absorption lasts more than that observed in other parts of the brain. Additionally, our study suggests no benefits of AIP mutation screening in sporadic patients with apoplexy.

Abstract
BACKGROUND Pituitary apoplexy is an acute syndrome of haemorrhage or infarction into the pituitary. The condition is relatively well-described. Less well-described is sub-acute presentation of the same condition. OBJECTIVE To compare the clinical presentation and natural history of subacute pituitary haemorrhage/infarction with pituitary apoplexy (acute). METHOD Retrospective analysis of a consecutive cohort of 55 patients (33 with pituitary apoplexy, 22 with subacute disease) presenting to University Hospital Plymouth between 1994 and 2019. Comparison of the clinical, endocrinological and radiological features at presentation. Comparison of clinical treatment and subsequent outcomes for the two groups. RESULTS There were no significant differences in predisposing factors for the two groups. Acute headache was more frequent in the acute group. Chronic headache was common in both groups prior to presentation. Low sodium was more common at presentation in the acute group (11/26 vs 2/19 P = 0.02) otherwise there were no differences in endocrine deficit at presentation. A significant proportion showed an improvement in endocrine function at follow up (acute 8/31, subacute 5/21 P = 1.0). MRI characteristics were variable at presentation and follow up in both groups. Ring enhancement with contrast was more frequent in acute (14/20 vs 3/11 P = 0.03). This appearance resolved at follow up in the majority. CONCLUSIONS Pituitary apoplexy has a characteristic and dramatic presentation. Subacute pituitary haemorrhage/infarction shows similar natural history and outcome. These conditions would appear to represent a spectrum of the same condition.

Abstract
Pituitary apoplexy is a life-threatening syndrome caused by acute infarction of the pituitary gland. The most common symptoms associated with pituitary apoplexy are headache, nausea, vomiting, visual symptoms, hypopituitarism, and altered mental status. Both oculomotor nerve palsy and hyponatremia are relatively rare complications of pituitary apoplexy. The treatment of pituitary apoplexy is controversial. We report a case of a 72-year-old man with severe headache, nausea, vomiting, confusion and left oculomotor nerve palsy, who was initially considered as posterior communicating artery aneurysm (PCOAA) based on the presenting symptoms. Initial biochemical evaluation showed severe hyponatremia, hormonal evaluation identified multiple pituitary hormone deficiency and enhanced magnetic resonance imaging showed a large pituitary adenoma with signs of hemorrhage. A diagnosis of pituitary apoplexy and secondary hypopituitarism was finally made. The patient was treated with intravenous hydrocortisone 100 mg twice daily and oral levothyroxine 100 mg once daily. Appropriate venous transfusion with sodium was also used concomitantly to correct hyponatremia. After seven days of treatment, the patient's serum electrolytes normalized and he gradually recovered alertness. Then, the patient underwent transsphenoidal surgery for tumor removal. Left ptosis and oculomotor nerve palsy completely recovered three months after surgery. Postoperatively, hormone replacement therapy was essential for the patient with 20 mg hydrocortisone and 50 mg levothyroxine once daily. During the last follow up 4 years later, the patient was still on hormonal replacement and in good condition. So, for patients with pituitary apoplexy, we have shown that a semi-elective surgery after conservative treatment when the patient becomes clinically stable and hypopituitarism has been corrected is a good approach.

Abstract
PURPOSE The management of pituitary apoplexy, a rare emergency neuroendocrine condition, is controversial. The aim of the present study is to compare the outcomes of patients with pituitary apoplexy managed either by a conservative or surgical approach. METHODS A retrospective cohort study including patients diagnosed between 2007 and 2018 in a tertiary French university hospital. Pituitary Apoplexy Score (PAS) was retrospectively applied in the perspective of therapeutic decision support. RESULTS Forty-six patients were treated for pituitary apoplexy either with conservative management (n = 27) or surgery (n = 19). At initial evaluation, visual field defects (VFD) and visual acuity impairment were more frequent in patients from the surgery group. At 1 year there were no statistical differences in the rates of complete/near-complete resolution of VFD (100 vs. 91.7%), visual acuity impairment (100 vs. 87.5%), and cranial nerve palsies (83.3 vs. 100%), between conservative and surgical treatment groups. There were more endocrine deficits at 1 year in the surgical group (p = 0.029). PAS (n = 41) was 3.4 on average in the early surgery group and 1.3 in the conservative treatment/delayed surgery group. Among patients with a score < 4, 31.3% were operated at first line and did not present better outcomes than patients managed conservatively. In all, 88.9% of patients with a score ≥ 4 underwent surgery. CONCLUSIONS PAS may be a reliable parameter for defining therapeutic strategy. Patients with non-severe and nonprogressive neuro-ophthalmological deficits can be managed conservatively without negative impact on outcomes, thus surgery should be reserved only for those patients with a PAS ≥ 4.

Abstract
OBJECTIVES (1) Describe presentation, management and outcomes of a single-centre series of patients with pituitary apoplexy. (2) Compare early and long-term outcomes of conservative and surgical management. (3) Identify predictive factors for visual recovery. METHODS Retrospective analysis of patients acutely managed by Sheffield's Neurosurgery over a 9-years period. Outcome comparison was made between 2 groups ('conservative' versus 'emergency') at early FU and 3 groups ('conservative' versus 'elective' versus 'emergency') at long-term FU. RESULTS Data from 30 patients (M:F = 2.8:1; mean age: 54 years; median FU: 31.5 months) were collected. 86,7% patients presented with visual disturbances (70% acuity, 50% field, 50% diploplia). 10 (33%) patients underwent emergency surgery and further 8 underwent delayed elective surgery.At early FU, resolution rates of VA (33% versus 38%), VF (40% versus 50%) and CN deficits (71% versus 40%) were not significantly different between groups.At long-term FU, resolution of VA (80% versus 20% versus 75%) and CN deficits (67% versus 50% versus 80%) was not significantly different between groups. Most patients who underwent surgery presented with severe VA deficit (20% versus 40% versus 63%) but severity of initial deficit wasn't correlated with long-term resolution.VF recovery rates showed significant difference between groups (p = 0.027): 67% versus 0% versus 88%.Endocrine outcomes were generally poor, regardless of the management strategy.Regarding possible predictive factors, age and tumour size correlated with visual outcomes. Especially in patients treated conservatively in the acute phase, no cases of complete resolution of VA or VF deficit were recorded when tumour was higher than 35 mm. CONCLUSIONS Good results are possible with conservative management in selected cases. Emergency surgery provides better visual outcomes. Decision-making process should be tailored to every single patient. We believe that a tumour vertical diameter >35 mm should tip the balance in favour of surgical management in presence of visual deficit.

Abstract
Background: Cerebral infarction caused by pituitary apoplexy (PA) is rare. To characterize the clinical features of cerebral infarction caused by PA, we performed a systematic review. Summary: The clinical symptoms are mainly sudden headache, hemiplegia, visual impairment, disturbance of consciousness, and ophthalmalgia in patients with cerebral infarction caused by PA. Treatment for this type of infarction is different from treatment for general acute cerebral infarction. Compared to patients who underwent emergency surgery and conservative treatment, patients treated with delayed surgery showed a better prognosis and a lower mortality rate. Compared to patients who underwent craniotomy or conservative treatment, patients who underwent transsphenoidal surgery (TSS) not only improved well but also showed a lower mortality rate. Key Messages: PA rarely causes cerebral infarction, which is a critical condition with a poor prognosis and is more common in men. Delayed surgery and TSS appear to confer a better prognosis in patients with this condition.

ICAR: endoscopic skull-base surgery. Int Forum Allergy Rhinol 2020; 9:S145-S365.

Abstract
BACKGROUND Endoscopic skull-base surgery (ESBS) is employed in the management of diverse skull-base pathologies. Paralleling the increased utilization of ESBS, the literature in this field has expanded rapidly. However, the rarity of these diseases, the inherent challenges of surgical studies, and the continued learning curve in ESBS have resulted in significant variability in the quality of the literature. To consolidate and critically appraise the available literature, experts in skull-base surgery have produced the International Consensus Statement on Endoscopic Skull-Base Surgery (ICAR:ESBS). METHODS Using previously described methodology, topics spanning the breadth of ESBS were identified and assigned a literature review, evidence-based review or evidence-based review with recommendations format. Subsequently, each topic was written and then reviewed by skull-base surgeons in both neurosurgery and otolaryngology. Following this iterative review process, the ICAR:ESBS document was synthesized and reviewed by all authors for consensus. RESULTS The ICAR:ESBS document addresses the role of ESBS in primary cerebrospinal fluid (CSF) rhinorrhea, intradural tumors, benign skull-base and orbital pathology, sinonasal malignancies, and clival lesions. Additionally, specific challenges in ESBS including endoscopic reconstruction and complication management were evaluated. CONCLUSION A critical review of the literature in ESBS demonstrates at least the equivalency of ESBS with alternative approaches in pathologies such as CSF rhinorrhea and pituitary adenoma as well as improved reconstructive techniques in reducing CSF leaks. Evidence-based recommendations are limited in other pathologies and these significant knowledge gaps call upon the skull-base community to embrace these opportunities and collaboratively address these shortcomings.

Abstract
BACKGROUND The management of pituitary apoplexy, caused by acute hemorrhage and/or infarction of a pituitary adenoma, is debated. OBJECTIVE To analyze clinical characteristics of patients undergoing endoscopic endonasal approaches (EEAs) for pituitary apoplexy. METHODS A retrospective review of patients at our institution from 2012 to 2018 undergoing EEA for pituitary apoplexy diagnosed clinically and with imaging/pathologic findings. Analysis included demographics, symptoms, neuroendocrine deficits, neuroimaging, complications, symptom resolution, and follow-up details. RESULTS Fifty patients (mean age, 53 years) were included. Preoperative symptoms included headache (86%), vision loss (62%), and cranial nerve paresis (40%). Mean tumor diameter was 2.7 cm and extrasellar extension was observed in 96% of tumors. Twenty-eight tumors were hemorrhagic (76%), 24 were necrotic (65%), and 13 (35%) had both features. Magnetic resonance imaging showed gross total resection in 58% of patients. Headache and vision loss improved in 87% and 86% of presenting patients. Cranial nerve paresis resolved in 72% of patients, partially improved in 11%, and remained unchanged in 17%. There were no deaths or carotid artery injuries. Surgical complications included postoperative cerebrospinal fluid leak (n = 4, 8%), epistaxis (n = 2, 4%), postoperative abscess (n = 1, 2%), and transient postoperative vision loss requiring reoperation (n = 1, 4%). Endocrinopathies improved in 21% of patients and panhypopituitarism persisted in 48% and developed in 6% of patients. Mean follow-up time was 26 months; 2 patients experienced recurrence. CONCLUSIONS EEA for pituitary apoplexy is effective in rapidly improving headache and visual symptoms. Although neuro-ophthalmic deficits often improve over time, panhypopituitarism persists in most patients after surgical resection.

Abstract
A 14-year-old girl was referred to our department because of headache and visual impairment following the resection of recurrent cardiac myxoma. Head magnetic resonance imaging (MRI) scan detected an intra- and supra-sellar tumor. Moreover, the patient showed the presence of spotty skin pigmentations on her cheeks and lower lip. Blood examination revealed hypothyrotropinemia, and ultrasonography results revealed multiple thyroid nodules. She was diagnosed with Carney complex (CNC). Her pituitary tumor was suspected as growth hormone (GH)-secreting adenoma, because overgrowth was observed in the patient. However, biochemical examinations, including oral glucose tolerance test, failed to show the characteristic findings of GH-secreting adenoma. In contrast, insulin tolerance test showed GH deficiency. Her visual impairment improved without performing decompression surgery, and the tumor size decreased, as per the MRI findings. Based on clinical course, the patient was diagnosed with pituitary apoplexy in pituitary adenoma, following which she was discharged. At 3 months after discharge, thyrotropin-releasing hormone loading test performed revealed low thyrotropin-stimulating hormone and thyroid hormone levels, and the patient was in a depressed mood. Therefore, l-T4 replacement was initiated, following which her GH secretory capacity gradually improved. Here, we report, to the best of our knowledge, the first case of a patient with pituitary apoplexy in CNC. Such condition must be identified in young patients with recurrent cardiac myxoma, and examinations, such as head MRI, must be performed.

Visual and Endocrine Recovery Following Conservative and Surgical Treatment of Pituitary Apoplexy: A Meta-Analysis. World Neurosurg 2019; 132:33-40.

Abstract
BACKGROUND Pituitary apoplexy (PA) can manifest with visual and endocrine defects. The literature lacks strong support for either surgical or conservative management with respect to symptomatic improvement of these deficits. This meta-analysis compared visual and endocrine outcomes in conservative and surgical treatment of PA. METHODS A systematic literature search was performed in PubMed, Cochrane, and Ovid MEDLINE for articles published between 1988 and 2018. Recovery outcomes were binarized, such that complete and partial improvements were combined as "improvement." Primary outcome variables evaluated via a binary random-effects model were improvements in endocrine dysfunction, visual field and acuity deficits, and ophthalmoplegia or ocular nerve palsy. RESULTS Of 483 published articles, 14 studies comprising 457 cases (259 surgical treatments and 198 conservative treatments) were included. On initial examination, 58% of patients had endocrine dysfunction, 37% had visual acuity or field deficit, and 47% had ophthalmoplegia or ocular nerve palsy. Evaluation of outcomes for surgically and conservatively treated patients yielded odds ratios of 0.609 (95% confidence interval [CI], 0.199-1.859; P = 0.383), 0.763 (95% CI, 0.307-2.374; P = 0.763), 1.167 (95% CI, 0.433-3.146; P = 0.760), and 0.801 (95% CI, 0.305-2.105; P = 0.653) for improvements in endocrine dysfunction, visual acuity dysfunction, visual field dysfunction, and ophthalmoplegia or ocular nerve palsy. CONCLUSIONS Both surgical intervention and conservative management of PA can lead to visual and endocrine recovery, although the management decision may heavily rely on severity of initial deficits. Treatment of PA can be multifaceted and tailored to the individual case and clinical judgment. Further investigation into appropriate intervention based on longitudinal outcome data is warranted.

Abstract
Pituitary apoplexy is a clinical condition with acute-onset headaches, vision loss, and/or pituitary dysfunction associated with a hemorrhagic or infarcted pituitary tumor or cyst. Treatment varies based on clinical presentation, although often urgent or emergent surgical resection is indicated. Conservative treatment strategies tend to be applied for more mild conditions of apoplexy. Overall outcomes may be similar in this less severe cohort. Acute-onset vision loss with apoplexy should be treated with urgent or emergent surgical evacuation of hematoma and resection of tumor when possible.

Abstract
PURPOSE OF REVIEW Pituitary apoplexy (PA) occurs in the setting of an infarction and/or hemorrhage of a pre-existing adenoma. The most common presenting symptom is a severe, sudden onset headache. However, the characteristics of headache in the setting of PA are varied and can sometimes mimic primary headache disorders. The purpose of this article is to review the various presentations of headache in PA. We also outline treatment options for persistent headaches following PA. RECENT FINDINGS A recent retrospective review of patients undergoing transsphenoidal resection of sellar lesions, including PA, found that gross total resection and short duration of preoperative headache were predictors of improvement in headaches postoperatively. This strengthens the importance of timely recognition of PA as potential etiology of headache. The most common presentation of PA is thunderclap headache; however, several other primary HA disorders have been described including status migraine, SUNCT, and paroxysmal hemicrania.

Abstract
OBJECTIVE Pituitary apoplexy is associated with visual, cranial nerve, and endocrine dysfunction. In this article, the results of surgical and conservative management of pituitary apoplexy in a single center are evaluated and a review of the literature is presented. METHODS A retrospective analysis was made of patients with pituitary apoplexy who underwent surgery or conservative management at our center between January 2007 and June 2017. Surgery was typically selected for patients who presented with acute deterioration of visual status and/or level of consciousness. Patients with no visual field deficit and those who had medical contraindications to undergo a surgical procedure because of previous comorbidities typically had conservative treatment. Baseline characteristics and clinical and radiologic outcomes were reviewed. A review of the literature (1990-2018) was performed according to PRISMA guidelines. Studies comparing the results of conservative and surgical management were identified. Visual, cranial nerve, and endocrine outcomes and tumor recurrence were analyzed. RESULTS Forty-nine patients (73.1%) were managed surgically and 18 (26.9%) conservatively. After careful case selection, patients underwent surgical or conservative treatment. Patients who underwent conservative treatment had fewer visual deficits. At diagnosis, visual deficit (38.8% vs. 75.5%; P = 0.008) and cranial nerve palsy (27.7% vs. 51%; P = 0.058) were less common in the conservative group. Conservative and surgical treatments had similar visual and cranial nerve improvement rates (75% vs. 58.3%, P = 0.63 and 75% vs. 69.2%, P = 1.0, respectively). In the conservative group, tumor shrinkage was observed in 76.4% of cases. The systematic review retrieved 11 studies. No significant difference between conservative and surgical treatment for clinical outcomes (visual field recovery, odds ratio [OR], 1.45; 95% confidence interval [CI], 0.72-2.92; cranial nerve recovery, OR, 2.30; 95% CI, 0.93-5.65; and hypopituitarism, OR, 1.05; 95% CI, 0.64-1.74) or tumor recurrence (OR, 0.68; 95% CI, 0.20-2.34) was observed. CONCLUSIONS A tailored approach to pituitary apoplexy, one that does not include an absolute need for surgery, is appropriate. Conservative management is appropriate in selected patients presenting without visual deficits.

Abstract
OBJECTIVE Pituitary apoplexy (PA) is an endocrinologic emergency characterized by headache, visual abnormalities, and hemodynamic instability in the context of hemorragic infarction of a pituitary adenoma. Our goal was to estimate the incidence, precipitating factors, clinical characteristics, and outcome of PA in a cohort of patients with nonfunctioning pituitary macroadenomas (NFPMAs). METHODS A retrospective, case-control study of 46 patients with PA and 47 controls matched for age, gender, and tumor invasiveness. Clinical, hormonal, and tumoral charactersitics, as well as the presence of potential precipitating factors and long-term outcome were evaluated using both bivariate and multivariate analysis. RESULTS The prevalence of PA was 8%. Cases and controls were similar in regards to the prevalence of diabetes, hypertension, use of antiplatelet agents, and the presence of headaches and visual field defects. Oculomotor paralysis was present in 18% of cases and in none of the controls (P = .001). Prior use of dopamine agonists was significantly more frequent among cases than in controls on both bivariate and multivariate analysis. Pituitary hormone deficiencies were more common among cases than in controls on bivariate but not on multivariate analysis. Early and late surgical treatment was carried out in 11 and 25 patients, respectively; 11 patients were managed conservatively. Visual and endocrine outcomes were similar among the 3 groups. CONCLUSION PA represents a life-threatening medical emergency. Prior use of dopamine agonists and the presence of oculomotor abnormalities clearly distinguished patients with NFPMA who developed PA from those who did not.

Pituitary Apoplexy in Long-Term Cabergoline User During Thrombocytopenia Due to Chemotherapy for Chronic Myelocytic Leukemia. World Neurosurg 2018; 120:290-295. [PMID: 30189305 DOI: 10.1016/j.wneu.2018.08.187] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2018] [Revised: 08/22/2018] [Accepted: 08/23/2018] [Indexed: 11/29/2022]
Abstract
BACKGROUND Pituitary apoplexy (PA) is a life-threatening syndrome. The usage of a dopamine agonist, such as bromocriptine or cabergoline, is considered a predisposing factor for PA, which commonly occurs 1.5 years within commencement. CASE DESCRIPTION A 64-year-old female with a >15-year history of cabergoline therapy for pituitary prolactinoma was referred to our department of neurosurgery after complaining of headache, blurred vision, diplopia, and ptosis for 3 days during hospital admission for chemotherapy of chronic myelocytic leukemia. Computed tomography and magnetic resonance imaging revealed findings indicative of PA. As the patient was experiencing thrombocytopenia related to chemotherapy, blood transfusion was preceded, and after a platelet count of 15.0 × 104/μL was confirmed, transnasal neuroendoscopic surgery was performed 5 days from the onset of symptoms. The majority of the prolactinoma was removed, and the prolactinoma in the cavernous sinus was intentionally left. The postoperative course was generally good. The ptosis and diplopia improved, and the blurred vision resolved. CONCLUSIONS PA related to dopamine agonist therapy can occur in cases of elevated bleeding tendency, even in long-term users, suggesting that attention should be paid in the administration of a dopamine agonist in the patient experiencing thrombocytopenia. Surgical intervention should be performed after the preoperative platelet number and adequate response to transfusion are confirmed, and the aggressive removal of prolactinoma in the cavernous sinus should be avoided to reduce the risk of hemorrhagic complications.

Abstract
PURPOSE To review the clinical and biochemical characteristics and clinical outcome of patients presenting with pituitary apoplexy to a tertiary centre. METHODS We retrospectively reviewed the clinical features, predisposing factors, biochemistry and clinical outcome of patients presenting with pituitary apoplexy to Imperial College Healthcare NHS Trust between 1991 to 2015. RESULTS We identified 64 patients with pituitary apoplexy (more complete clinical records were available in 52 patients). The median age at presentation was 46.7 years (IQR 31.5-57.0 years). Pituitary apoplexy was the first presentation of pituitary disease in 38/52 of patients and predisposing factors were identified in 28/52. Pituitary apoplexy predominantly occurred in patients with non-functioning pituitary adenomas (47/52). Headache was most commonly described as sudden-onset, severe, lateralising to the frontal or temporal regions. Symptoms of meningeal irritation were reported in 7/18 and visual abnormalities in 22/35. A pre-treatment serum cortisol <100nmol/l was recorded in 12/31 of patients. All patients with visual disturbance had some resolution of their visual symptoms whether managed surgically (14/14) or conservatively (5/5), although pituitary endocrine function did not fully recover in any patient. CONCLUSIONS In conclusion, these data describe the clinical features of pituitary apoplexy to aid the clinician in diagnosing this rare emergency presentation of pituitary disease. Prospective multicentre studies of the presentation of pituitary apoplexy are required to further characterise presentation and outcomes.

Abstract
RATIONALE Pituitary apoplexy (PA) is a syndrome caused by acute hemorrhage or infarction of the pituitary gland, generally within a pituitary adenoma. PA following spinal surgery is a very rare complication and may be difficult to diagnose. However, early diagnosis of PA is essential for the timely treatment of pan-hypopituitarism and prevention of severe neurologic complications. PATIENT CONCERNS A 73-year-old man had a posterior lumbar fusion surgery over a period of 8 hours on prone position. The patient complained of severe intractable headache accompanied by ophthalmalgia and ptosis on right eye 2 days after the surgery. DIAGNOSIS Brain magnetic resonance imaging revealed a 1.3 × 2.6 × 2 cm mass in the sellar fossa and suprasellar region and the laboratory tests indicated pan-hypopituitarism. INTERVENTIONS High-dose intravenous steroid therapy and trans-sphenoidal hypophysectomy were performed. OUTCOMES Pathological evaluation of the surgical specimen revealed a pituitary adenoma with total necrosis, indicating that the PA occurred because of tumor infarction. The patient recovered fully after resection of the pituitary adenoma and hormonal therapy. LESSONS Even though the incidence is low, PA has been related to blood pressure fluctuations or vasospasm during surgery. PA should be considered during differential diagnosis in cases of postoperative severe headache or ophthalmic complications.
