World Neurosurg 2024; 185:e532-e541. [PMID: 38373688 DOI: 10.1016/j.wneu.2024.02.069] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2023] [Revised: 02/11/2024] [Accepted: 02/12/2024] [Indexed: 02/21/2024]
Abstract
BACKGROUND The endoscopic approach has gained popularity in cerebrospinal fluid (CSF) rhinorrhea repair with high success rates, yet recurrence is frequent. We analyzed our cases to determine the outcomes of endoscopic repair of CSF rhinorrhea and the effect of several perioperative factors on the success of repair. METHODS A retrospective review of 50 patients who underwent endoscopic repair of CSF rhinorrhea between January 2013 and July 2023 was performed, collecting details of presentation, surgery, and postoperative period. RESULTS The most frequent etiology was nontraumatic CSF rhinorrhea (76%), in which the defect was most commonly located at the left cribriform plate, followed by traumatic CSF rhinorrhea (24%), in which sphenoid defects were most frequent. Traumatic CSF rhinorrhea was more common among male patients and was significantly associated with anosmia. Success rate at first repair attempt was 84%. Persistent CSF rhinorrhea was present in 3 patients (6%), and 5 patients (10%) developed recurrence of CSF rhinorrhea. Overall, 7 patients required reoperation, with 100% success rate after the second surgery. The use of 3-layered repair with fat, fascia lata, and mucosal flap was protective against repair failure, whereas bilateral defects and duration of symptoms >1 year were significantly associated with repair failure. The use of lumbar drain did not demonstrate a difference in repair success rate. CONCLUSIONS Endoscopic repair of CSF rhinorrhea appears to be safe and effective when performed with accurate localization of the site of the lesion and multilayered repair. Potential predictors of recurrence include bilateral and long-standing defects.

Abstract
PURPOSE Giant prolactinomas (GP) are rare tumors accounting for 4.3% of prolactinomas, with paucity of literature from India. We aim to describe clinical, biochemical, radiological, and treatment outcomes in a large series of Asian-Indian patients with GP. METHODS A single-center retrospective analysis of GPs (n=84), age-based (adults: 66 versus pediatric: 18) and gender-based (males: 64 versus females: 20) comparison was done. RESULTS The mean age at presentation was 34.1±13years, and 64 (76.2%) were males. Males were younger at presentation (32.1±12.2 versus 40.1±13.8years, P: 0.01). The majority presented with mass-effect-related manifestations (visual disturbances: 91.6%, headache: 84.5%) and/or hypogonadism (98.7%). At baseline, largest tumor dimension was 5.3±1.0cm, and serum prolactin was 8343 (3865.5-12,306) ng/mL; most (94.6%) had gonadal axis involvement. Dopamine-agonist (DA) as first-line therapy (45/67, 67.2%) achieved normoprolactinemia (maximum cabergoline dose: 2.0±1.2mg/week) in 36/45 (80%) and tumor response (≥50% reduction) in 36/37 (97.3%) patients at the last follow-up (median duration: 33 [14.5-53.5]months). Notably, gonadal axis recovery was poor (6/30, 20%) despite normoprolactinemia post-DA monotherapy. At latest follow-up, secondary hypothyroidism (32.5% versus 82.6%, P: 0.001) and central hypocortisolism (5.6% versus 42.9%, P: 0.007) were less frequent in DA monotherapy (n=43) than in multimodal therapy group (n=23). The proportion of males (94.4% versus 71.2%, P: 0.04) was higher in the pediatric age group, with DA-induced (first-line) normoprolactinemia observed in 66.7% of them. CONCLUSION GP has male predominance, DA as first-line therapy normalized prolactin in four-fifths of patients with better preservation of HPT and HPA axes in patients with DA monotherapy.

Abstract
BACKGROUND Dopamine agonist-induced cerebrospinal fluid (CSF) rhinorrhea is an uncommon treatment-related complication arising in 6.1% of prolactinoma patients treated with dopamine agonists. Locally invasive prolactinomas may create CSF fistulae through formation of dural and osseous skull base defects. Tumor shrinkage secondary to dopamine agonist therapy unmasks skull base defects, thus inducing CSF rhinorrhea. In these cases, repair of the leak may be achieved through collaborative surgical intervention by rhinologists and neurosurgeons. Multiple variables have been investigated as potential contributors to the risk of CSF rhinorrhea development in medically treated prolactinoma patients, with little consensus. OBJECTIVE The primary aim of our study was the characterization of risk factors for CSF rhinorrhea development following dopamine agonist treatment. METHODS A systematic review of the literature was conducted to identify cases of CSF rhinorrhea following dopamine agonist treatment of prolactinoma. The clinical history, radiographic findings and treatment outcomes are discussed. RESULTS Fifty-four patients with dopamine agonist-induced CSF rhinorrhea were identified across 23 articles published from 1979 to 2019. Description of diagnostic imaging [computed tomography (CT)/magnetic resonance imaging (MRI)] was not provided for 18/54 subjects. For the 36 cases that described prolactinoma appearance on CT or MRI, invasion of the cavernous sinuses was reported in 13 (36.1%) and invasion of the sphenoid sinus was reported in 18 (50%). CONCLUSION Based on our systematic review, we propose that CT findings of osseous erosion of the sella or the anterior skull base may predict dopamine agonist-induced CSF rhinorrhea. We recommend obtaining a thin-slice CT of the sinuses in cases with MRI evidence of sphenoid involvement.

Abstract
PURPOSE Giant prolactinoma (GP) in childhood and adolescence is a rare entity with scarce literature. We aimed to describe clinical features, biochemistry, radiology, genetics, management, and outcome in pediatric (≤ 20 years) GP. METHODS Retrospective record review of 18 pediatric GP patients from our center and systematic review including these and 77 from the literature (total cohort: 95). RESULTS GP constituted 20% of our pediatric prolactinoma cohort. In the total cohort (age: 15.4 ± 3.5 years), the majority (77, 82.8%) were males. Mass effect symptoms (88.6%), and pubertal delay/arrest in males (82.1%) were frequent. Median basal prolactin was 8649 (3246-17,532) ng/ml and the maximum tumor dimension was 5.5 ± 1.5 cm. MEN1 and AIP mutations were noted in 7 (21.9%) and 6 (18.8%) patients, respectively. Males with central hypogonadism had baseline bi-testicular volume of 20.2 ± 8.4 cc, lower LH than FSH (-2.04 ± 0.9 vs. -0.7 ± 1.6 SDS, p = 0.0075), and mostly, normal inhibin B. Majority (49/76, 64.5%) received dopamine agonist (DA) as first-line treatment with additional therapy in 35% (17/49). DA monotherapy arm had less frequent central hypothyroidism (42.9% vs 87.1%, p = 0.002) and central adrenal insufficiency (7.1% vs 66.7%, p = 0.0003) than multimodal therapy. A smaller tumor dimension (4.7 vs. 5.7 cm, p = 0.04) was associated with normoprolactinemia on DA monotherapy and AIP mutations (33.3% vs. nil, p = 0.02) with multimodal therapy. CONCLUSION GP is characterized by male predominance with frequent delay/arrest of puberty (82%), but relative sparing of the FSH-inhibin B axis in boys. DA monotherapy may be preferred as the first-line therapy in pediatric GP.

Abstract
Prolactinomas are the commonest form of pituitary neuroendocrine tumor (PitNET), representing approximately half of such tumors. Dopamine agonists (DAs) have traditionally been the primary treatment for the majority of prolactinomas, with surgery considered the second line. The aim of this review is to examine the historical and modern management of prolactinomas, including medical therapy with DAs, transsphenoidal surgery, and multimodality therapy for the treatment of aggressive prolactinomas and metastatic PitNETs, with an emphasis on the efficacy, safety, and future directions of current therapeutic modalities. DAs have been the mainstay of prolactinoma management since the 1970s, initially with bromocriptine and more recently with cabergoline. Cabergoline normalizes prolactin in up to 85% of patients and causes tumor shrinkage in up to 80%. Primary surgical resection of microprolactinomas and enclosed macroprolactinomas performed by experienced pituitary neurosurgeons have similar remission rates to cabergoline. Aggressive prolactinomas and metastatic PitNETS should receive multimodality therapy including high dose cabergoline, surgery, radiation therapy (preferably using stereotactic radiosurgery where suitable), and temozolomide. DAs remain a reliable mode of therapy for most prolactinomas but results from transsphenoidal surgery in expert hands have improved considerably over the last one to two decades. Surgery should be strongly considered as primary therapy, particularly in the setting of microprolactinomas, non-invasive macroprolactinomas, or prior to attempting pregnancy, and has an important role in the management of DA resistant and aggressive prolactinomas.

Abstract
The current treatment paradigm for prolactinomas involves dopamine agonist (DA) therapy as the first-line treatment, with surgical resection reserved for cases where there is DA failure due to resistance or intolerance. This review highlights how DA therapy can be optimised to overcome its increasingly recognised pitfalls, whilst also addressing the potential for expanding the use of surgery in the management of prolactinomas. The first part of the review discusses the limitations of DA therapy, namely: DA resistance; common DA side effects; and the rare but serious DA-induced risks of cardiac valvulopathy, impulse control disorders, psychosis, CSF rhinorrhoea and tumour fibrosis. The second part of the review explores the role of surgery in prolactinoma management with reference to its current second-line position and recent calls for surgery to be considered as an alternative first-line treatment alongside DA therapy. Randomised trials comparing medical vs surgical therapy for prolactinomas are currently underway. Pending these results, a low surgical threshold approach is herein proposed, whereby DA therapy remains the default treatment for prolactinomas unless there are specific triggers to consider surgery, including concern regarding DA side effects or risks in vulnerable patients, persistent and bothersome DA side effects, emergence of any serious risks of DA therapy, expected need for long-term DA therapy, as well as the traditional indications for surgery. This approach should optimise the use of DA therapy for those who will most benefit from it, whilst instituting surgery early in others in order to minimise the cumulative burden of prolonged DA therapy.

Abstract
Multiple endocrine neoplasia type 1 (MEN1) is a rare autosomal dominant disorder characterized by tumors of parathyroid, anterior pituitary, and pancreatic islet cells. Pituitary adenomas in MEN1 can be aggressive and invade surrounding structures including the skull base. However, acute bacterial meningitis in patients with newly diagnosed macroprolactinomas is an exceptional finding. We present the case of a young man with suppurative meningitis complicating an invasive macroprolactinoma as the initial manifestation of MEN1. A 33-year-old male was admitted to the hospital with fever, headache, and nuchal rigidity and subsequently diagnosed with Haemophilus influenzae bacterial meningitis. Computed tomography (CT) and subsequent magnetic resonance imaging (MRI) of the sella turcica revealed a 5 x 3.5 cm pituitary mass invading both cavernous sinuses and the left sphenoid sinus. Laboratory evaluation was notable for significantly elevated serum prolactin level (2,484 ng/mL, 2.6-13.2) and evidence of hypopituitarism. Primary hyperparathyroidism was indicated by hypercalcemia (13.5 mg/dL, 8.5-10.5), low serum phosphorus (2.0 mg/dL, 2.5-4.9), and elevated intact parathyroid hormone (PTH) level (290 pg/mL, 15-60). No visual field deficits were identified. The patient was managed with hydrocortisone, levothyroxine, and cabergoline. However, cerebral spinal fluid (CSF) rhinorrhea compelled subtotal transsphenoidal resection of the tumor and repair of the CSF leak. Three-and-a-half gland parathyroid resection was performed after recovery from pituitary surgery and successfully treated hypercalcemia. Abdominal MRI revealed a 1.2 cm cystic mass in the neck of the pancreas, and pancreatic polypeptide was approximately fourfold elevated. A clinical diagnosis of MEN1 was made based on the occurrence of macroprolactinoma, multiple parathyroid adenomas, and pancreatic findings. This case appears to be the first in which bacterial meningitis was the initial presentation of an invasive macroprolactinoma in a patient with MEN1.

Abstract
Predicting dopamine agonist resistance in patients with macroprolactinoma is essential for clinicians to prevent treatment failure and subsequent complications such as medication-induced cerebrospinal fluid (CSF) rhinorrhea. We evaluated the features of patients with cabergoline resistance and CSF rhinorrhea in patients with prolactinomas with prolactin levels ≥1000 ng/mL. A total of 140 patients who were newly diagnosed with prolactinoma secreting only prolactin ≥1000 ng/mL and treated with cabergoline for the first time were included in this study. Based on the hormonal and radiologic response of the prolactinoma, the patients were divided into responders and non-responders. Non-responders (36/140, 25.8%) included a higher number of patients receiving hormone replacement than responders (responders, n (%) = 12(11.5) vs. non-responders = 13(36.1), p = 0.001). In propensity score matching analysis, patients who developed CSF rhinorrhea presented more frequent hormone deficiency than responders regardless of initial cabergoline dose. Hormone deficiency was associated with a greater odds ratio for the risk of non-responders (adjusted odds ratio = 5.13, 95% CI 1.96-13.46, p = 0.001). Cabergoline was effective in bioactive macroprolactinoma. Furthermore, initial cabergoline dose was not significantly associated with long-term responsiveness and development of CSF rhinorrhea but the hypopituitarism was independently associated with an increased risk of cabergoline resistance and CSF rhinorrhea.

Abstract
Cerebrospinal fluid (CSF) rhinorrhea is a rare complication of macroprolactinomas that, in the vast majority of cases, is subsequent to either medical or surgical intervention. Here, we present the successful management of a rare case of spontaneous, noniatrogenic CSF rhinorrhea in a patient with an untreated macroprolactinoma. A 27-year-old man with no significant medical history presented with six months of persistent CSF rhinorrhea, which was confirmed by testing for beta-2-transferrin. He had had decreased libido since adolescence and impaired growth of secondary sexual characteristics. Workup revealed an elevated prolactin level, and imaging demonstrated erosion of the anterior sellar floor and soft tissue within the sphenoid sinus, concerning for tumor. The patient underwent surgical repair of the CSF leak via a transnasal transsphenoidal approach, with resection and biopsy of tumor material within the sinus. No tumor was noted within the sella itself. The patient tolerated the procedure well and had subsequent normalization of his prolactin level with no further CSF egress. Spontaneous noniatrogenic CSF rhinorrhea, although rare, should be considered in the differential diagnosis of invasive pituitary macroadenomas, especially prolactinomas. The mechanism of CSF leak from a prolactinoma is not completely understood, but the CSF leak should be urgently repaired through a transnasal transsphenoidal approach. Concurrently, tumor resection should be performed and a postoperative lumbar puncture or lumbar drain should be considered to reinforce the skull base reconstruction.

Abstract
First-line treatment of prolactinoma is usually medical, based on dopamine agonists receptors, mainly cabergoline. The classical side-effects of cabergoline (low blood pressure and nausea) have been well known since it was first introduced. Other side-effects, however, are more controversial or simply less frequent, but need to be considered during monitoring. This review will focus on these side-effects: cardiac valvular fibrosis, pleural, pericardial and retroperitoneal fibrosis, addictive/compulsive behaviors, and risks secondary to significantly decreased tumor volume. We will also describe how such side-effects should be monitored and managed. In our opinion, the low prevalence of these side-effects should not cast doubt on the role of cabergoline in the therapeutic algorithm of prolactinoma.

Abstract
Objective To describe 2 spontaneous cerebrospinal fluid (CSF) leaks complicating treatment of macroprolactinoma (MPRL) with dopamine agonist (DA) therapy. Methods We present the 2 cases of spontaneous, DA-related CSF leaks. Prolactin levels were used to assess hyperprolactinemia. Beta-2 transferrin was tested in rhinorrhea fluid, and magnetic resonance imaging was used to assess the sella. Results Case 1 was a 45-year-old woman with a history of MPRL, recently started on bromocriptine at 15 mg/day, presented with clear rhinorrhea, headache, and nuchal rigidity. Magnetic resonance imaging showed a large sellar lesion extending into the cavernous sinuses, posterior sphenoid sinuses, and suprasellar cistern. Computed tomography revealed areas concerning for bony erosion, likely representing leak sites, and the rhinorrhea fluid was positive for beta-2 transferrin, confirming the CSF source. Empiric antibiotics for meningitis were given and she underwent urgent neuroendoscopic, transsphenoidal CSF leak repair and debulking of the pituitary mass. Case 2 was a 55-year-old man with a 10-year history of untreated MPRL who was started on bromocriptine at 5 mg/day 2 weeks prior to admission. He presented with clear rhinorrhea and a metallic taste in his mouth, worse with the Valsalva maneuver. Imaging confirmed clinical suspicion and he was taken for surgery. A high-flow CSF leak was encountered once the tumor was debulked. This was repaired with an abdominal fat pad graft. Both patients developed diabetes insipidus and required postoperative adjuvant DA therapy. Conclusion Spontaneous CSF leaks can complicate medical therapy of large MPRL with underlying skull defects, typically within weeks of initiation of DA. This should prompt clinicians to educate patients about the symptoms of potential CSF rhinorrhea and encourage them to promptly report them.

Abstract
PURPOSE Renewed interest in transsphenoidal surgery (TSS) as a therapeutic option for prolactinomas has emerged. METHODS Based on contemporary literature and own experience, the changing role of surgery for treatment of prolactinomas is discussed. RESULTS Today, TSS is performed by minimally invasive microscopic or endoscopic techniques. Normoprolactinemia is obtained in 71-100% of patients with microprolactinomas by TSS. Almost equal results are found in circumscribed intrasellar macroprolactinomas. In experienced hands, pituitary function is preserved in TSS. The risk of cardiac valve disease is still a concern with ergot-derived dopamine-agonists (DAs) in patients requiring long-term, high-dose dopamine-agonist (DA) treatment. Cost-utility analysis favors TSS over DA treatment. The possible negative impact of DA treatment on future surgical results is still a controversial and unsettled issue. In patients who wish to become pregnant, the advantages of microprolactinoma removal to avoid DAs and macroprolactinoma debulking to avoid symptomatic enlargement during pregnancy should be discussed with the patients. Young patients' age is an argument for surgery to circumvent the unpredictable sequelae of long-term DA treatment. Surgery should be discussed in male gender because of a higher likelihood of DA resistance and aggressive behavior of prolactinoma. CONCLUSION Given excellent results of TSS and concerns about medical treatment, the scale of indications for TSS as an alternative to DAs has increased. The patient's wishes concerning a chance at a cure with TSS instead of a long-term treatment with DAs has become an important and accepted indication. With DA medication and TSS, two effective treatment modalities for prolactinomas are available that can be used in a complementary fashion.

Abstract
Cases of spontaneous CSF leak associated with pituitary tumor apoplexy are uncommon in the literature with pneumocephalus or pneumosella being rare, especially spontaneous occurrence of pneumocephalus being extremely rare. We present a case of pituitary macroadenoma apoplexy resulting in spontaneous CSF leak and a large volume of intra-tumoral gas. A 65-year-old female presented with severe headache, profuse rhinorrhea and acute vision loss and was found to have a large sellar and suprasellar lesion with air and hemorrhage with mild peripheral enhancement. The patient underwent trans-sphenoidal tumor resection and repair of skull base for CSF leak with nasoseptal flap placement. Pathology demonstrated a pituitary adenoma exhibiting immunoreactivity for ACTH. To our best knowledge, our case is the first report of features of pituitary tumor apoplexy with hemorrhage and pneumosella, which could be summarized by the term "pneumo-apoplexy".

Abstract
Cerebrospinal fluid (CSF) leakage can lead to brain and spine pathologies and there is an urgent need for a rapid diagnostic method for determining CSF leakage. Beta-2 transferrin (β2TF), asialotransferrin, is a specific CSF glycoprotein biomarker used to determine CSF leakage when distinguished from serum sialotransferrin (sTF). Methods: We detected β2TF using an immunochromatographic assay (ICA), which can be potentially developed as a point-of-care (POC) testing platform. Sialic acid-specific lectin selectively captures sTF in multiple deletion lines within an ICA test strip, enabling the detection of β2TF. A sample pre-treatment process efficiently captures excess sTF increasing sensitivity for CSF leakage detection. Results: An optimal cut-off value for determining the presence of CSF in test samples was obtained from receiver operating characteristic (ROC) analysis of the ratio of the test signal intensity and the deletion lines. On 47 clinical samples, ICA test strips discriminated CSF positive from negative samples with statistically significant (positive versus negative t-test; P =0.00027). Additional artificial positive samples, prepared by mixing CSF positive and negative clinical samples, were used as a further challenge. These positive samples were clearly discriminated from the negative samples (mixture versus negative t-test; P =0.00103) and CSF leakage was determined with 97.1% specificity and 96.2% sensitivity. Conclusions: ICA represents a promising approach for POC diagnosis of CSF leakage. While requiring 70 min assay time inconvenient for POC testing, our method was significantly shorter than conventional electrophoresis-based detection methods for β2TF.

Abstract
Prevalence and incidence of prolactinomas are approximately 50 per 100,000 and 3-5 new cases/100,000/year. The pathophysiological mechanism of hyperprolactinemia-induced gonadotropic failure involves kisspeptin neurons. Prolactinomas in males are larger, more invasive and less sensitive to dopamine agonists (DAs). Macroprolactin, responsible for pseudohyperprolactinemia is a frequent pitfall of prolactin assay. DAs still represent the primary therapy for most prolactinomas, but neurosurgery has regained interest, due to progress in surgical techniques and a high success rate in microprolactinoma, as well as to some underestimated side effects of long-term DA treatment, such as impulse control disorders or impaired quality of life. Recent data show that the suspected effects of DAs on cardiac valves in patients with prolactinomas are reassuring. Finally, temozolomide has emerged as a valuable treatment for rare cases of aggressive and malignant prolactinomas that do not respond to all other conventional treatments.

Abstract
A 21 year-old woman was found to have a pituitary macroadenoma following an episode of haemophilus meningitis. Biochemical TSH and GH excess was noted, although with no clear clinical correlates. She was treated with a somatostatin analogue (SSA), which restored the euthyroid state and controlled GH hypersecretion, but she re-presented with a further episode of cerebrospinal fluid (CSF) leak and recurrent meningitis. Histology following transsphenoidal adenomectomy revealed a Pit-1 lineage plurihormonal adenoma expressing GH, TSH and PRL. Such plurihormonal pituitary tumours are uncommon and even more unusual to present with spontaneous bacterial meningitis. The second episode of CSF leak and meningitis appears to have been due to SSA therapy-induced tumour shrinkage, which is not a well-described phenomenon in the literature for this type of tumour. Learning points: Pit-1 lineage GH/TSH/PRL-expressing plurihormonal pituitary adenomas are uncommon. Moreover, this case is unique as the patient first presented with bacterial meningitis. Inmunohistochemical plurihormonality of pituitary adenomas does not necessarily correlate with biochemical and clinical features of hormonal hypersecretion. Given that plurihormonal Pit-1 lineage adenomas may behave more aggressively than classical pituitary adenomas, accurate pathological characterization of these tumours has an increasing prognostic relevance. Although unusual, a CSF leak and meningitis may be precipitated by SSA therapy of a pituitary macroadenoma via tumour shrinkage.

Abstract
Macroprolactinoma has the potential to cause base of skull erosion and often extends into the sphenoid sinus. Rapid shrinkage of this invasive tumor following dopamine agonist therapy has been postulated to cause unplugging of the eroded area, leading to cerebrospinal fluid leakage. To the best of our knowledge, the occurrence of spontaneous cerebrospinal fluid leak in treatment-naive prolactinomas is very rare, the majority of which involve undiagnosed macroprolactinomas. We describe here a lady presented late with giant macroprolactinoma, complicated by cerebrospinal fluid leakage. This case raised the dilemma in the management pertaining to the role of either pharmacotherapy or surgical intervention, or combination of both. As she strictly refused surgery, she was treated with bromocriptine which was later changed to cabergoline. On follow-up, there was cessation of cerebrospinal fluid leak, marked reduction of serum prolactin level, and imaging evidence of tumor shrinkage. The majority of patients with medically induced cerebrospinal fluid leakage will require surgical procedures to overcome this complication; however, there are isolated cases of leakage resolution on continuing dopamine agonist therapy while awaiting surgery. The use of dopamine agonist does not necessarily cause worsening of cerebrospinal fluid leakage and instead may produce spontaneous resolution as in this case.

Abstract
Objective Cerebrospinal fluid (CSF) rhinorrhea following medical management of prolactinoma is a rare complication. We evaluated the clinical background of this condition, identify potential risk factors, and discuss the management options and challenges involved. Methodology We retrospectively reviewed clinical details of patients who were treated for CSF leaks among patients treated for prolactinoma between 2013 and 2017. Results Seven patients were treated for CSF rhinorrhea in the context of prolactinoma, with the age range between 24 and 56 years. Six patients had CSF leak following initiation of cabergoline, while one patient presented with CSF rhinorrhea. The time of onset of leak following medical treatment ranged from 14 days to 5 years. The mean preoperative serum prolactin level was 12,638 ng/mL (range: 1,000-26,287 ng/mL). All patients underwent repair of skull base defect. (four endoscopic, two microscopic, and one bifrontal craniotomy). The site of defect in the majority of patients was the sellar floor. Two patients who were initially managed with acetazolamide alone, eventually required surgical repair. Three patients were cured of CSF leak with a single procedure. Three patients had to undergo re-exploration and endoscopic repair after their first surgery failed. Two patients required lumboperitoneal (LP) shunt after a failed endoscopic transsphenoidal repair. Conclusion Surgical management for medically-induced CSF rhinorrhea is necessary; however, it can pose significant issues. Endoscopic repair of the defect should be considered at the earliest. Multiple surgical procedures are often required because of skull base erosion. LP shunt can be considered if CSF leak persists following multiple surgeries.

Abstract
PURPOSE Although several reports have addressed cerebrospinal fluid (CSF) rhinorrhea following dopamine agonist (DA) therapy of macroprolactinomas, further study is warranted for this relatively uncommon entity. Toward this aim, our retrospective series and review of literature further clarifies recommendations in treatment of this rare problem. METHODS We retrospectively reviewed all macroprolactinoma cases in our hospital for a 15-year period. Our systematic search of PubMed identified original articles and reviews of all macroprolactinoma cases with an associated medication-induced CSF leak. RESULTS Five patients with drug-induced CSF leak were identified; four of these patients received cabergoline therapy an average of 6 weeks before the onset of rhinorrhea and then underwent surgical repair of the CSF leak. Of 35 published studies included, we identified 60 patients with medication-induced CSF leak. Medical therapy included bromocriptine in 34 patients, cabergoline in 21 patients, and use of both DAs in two patients. Three cases did include complete diagnostic and treatment data. Median time from initiation of the DA treatment to occurrence of rhinorrhea was 6 weeks. For CSF rhinorrhea, 49 patients underwent surgical repair (38 by the transnasal approach) and seven patients were treated nonoperatively. CONCLUSION Baseline skull base erosion in macroprolactinomas in combination with subsequent tumor shrinkage induced by DA therapy may result in spontaneous CSF rhinorrhea. Therefore, such patients should be advised about and monitored for this potential setback. Once CSF leak is diagnosed, prompt treatment must be carried out to avoid infectious complications. Transnasal surgery appears the most effective therapeutic approach.

Abstract
Cerebrospinal fluid (CSF) rhinorrhea is rarely reported as the first presenting feature of giant invasive macroprolactinomas. Cerebrospinal fluid rhinorrhea is usually reported as a complication of trauma, neurosurgical, and skull-based procedures (such as pituitary surgery or radiations), and less frequently after medical treatment with dopamine agonists (DAs) for macroprolactinomas. This phenomenon results from fistula creation that communicates between the subarachnoid space and the nasal cavity. Meanwhile, pneumocephalus is another well-recognized complication after transsphenoidal surgery for pituitary macroadenomas. This entity may present with nausea, vomiting, headache, dizziness, and more seriously with seizures and/or a decreased level of consciousness if tension pneumocephalus develops. Case reports about the occurrence of spontaneous pneumocephalus after medical treatment with DAs without prior surgical interventions are scarce in the literature. Our index case is a young man who was recently diagnosed with a giant invasive prolactin-secreting pituitary macroadenoma with skull base destruction. A few months before this diagnosis, he presented with spontaneous CSF rhinorrhea with no history of previous medical or surgical treatment. In this case report, we report an uncommon presentation for giant invasive macroprolactinoma with a CSF leak treated with cabergoline that was subsequently complicated by meningitis and pneumocephalus. This is a very rare complication of cabergoline therapy, which occurred approximately 1 month after treatment initiation.

Abstract
At present, pharmacological therapy of prolactinomas with dopamine agonists (DAs) is considered the treatment of choice. In most cases, giant prolactinomas respond to treatment with dopamine agonists and decrease in size during the first months of the treatment. One of the rare but dangerous complications of conservative treatment of prolactinomas with invasive growth is cerebrospinal fluid rhinorrhea. MATERIAL AND METHODS We present a retrospective analysis of 15 patients with macropropactinomas who underwent surgery for cerebrospinal fluid rhinorrhea developed due to primary therapy with dopamine agonists at the Burdenko Neurosurgical Institute (BNI) in the period between 2005 and 2015. All patients had large and giant tumors (according to the classification adopted at the BNI). When cerebrospinal fluid rhinorrhea was detected, patients were hospitalized to the BNI for examination, detection of a CSF fistula, reconstruction of a defect, and resection (if possible) of the tumor. RESULTS In the period between 2005 and 2015, 15 patients (8 males and 7 females) with prolactinomas of a large and giant size at the onset of conservative therapy underwent surgery for cerebrospinal fluid rhinorrhea at the BNI. All patients underwent transnasal reconstruction of a skull base defect, with 13 out of 15 patients undergoing simultaneous resection of the tumor. After tumor resection, reconstruction was performed using auto-fat, fascia, and glue (in 8 cases). In the remaining cases, apart from auto-fat, fascia, and glue, a mucoperiosteal flap and auto-bone were used. Fourteen patients were followe-up. In 13 cases, there was no relapse of cerebrospinal fluid rhinorrhea after skull base reconstruction. In 1 case, there was a relapse of cerebrospinal fluid rhinorrhea. CONCLUSION Conservative treatment of patients with giant prolactinomas should be performed under regular control of ENT doctors and neurosurgeons for timely detection and surgical treatment of cerebrospinal fluid rhinorrhea.

Abstract
Acromegaly, a rare disease due to growth hormone (GH) hypersecretion by a pituitary adenoma, is associated with severe comorbidity and premature death if not adequately treated. The usual first-line treatment is surgery. Various drugs, including somatostatin receptor ligands, dopamine agonists and GH receptor antagonists, are now available for use if surgery fails to suppress GH/IGF-I hypersecretion. Cabergoline, now the preferred dopamine agonist for treating hyperprolactinemia, is also used off-label for treating acromegaly. Cabergoline monotherapy is reported to normalize IGF-I levels in more than one-third of patients with acromegaly. When a somatostatin receptor ligand proves ineffective, cabergoline add-on therapy normalizes the IGF-I level in 40-50% of patients. Finally, when combined with the GH receptor antagonist pegvisomant in patients with mild uncontrolled disease, cabergoline helps to achieve normal IGF-I levels while avoiding the need for high-dose pegvisomant. Cabergoline is also inexpensive and well tolerated; in particular, it does not appear to promote heart valve disease.

Abstract
Prolactinomas are the most common form of endocrinologically active pituitary adenoma; they account for ∼ 45% of pituitary adenomas encountered in clinical practice. Giant adenomas are those > 4 cm in diameter. Less than 0.5% of pituitary adenomas encountered in neurosurgical practice are giant prolactinomas. Patients with giant prolactinomas typically present with highly elevated prolactin levels, endocrinologic disturbances, and neurologic symptoms from mass-induced pressure. Described here is an unusual case of a giant prolactinoma presenting with neck pain and structural compromise of the occipital condyles. Transnasal biopsy of the nasopharyngeal portion of the mass obtained tissue consistent with an atypical prolactinoma with p53 reactivity and a high Ki-67 index of 5%. Despite the size and invasiveness of the tumor, the patient had resolution of his clinical symptoms, dramatic reduction of his hyperprolactinemia, and near-complete disappearance of his tumor following medical treatment.

Abstract
Therapeutic shrinkage of prolactinomas with dopamine agonists achieves clinical benefit but can expose fistulae that have arisen as a result of bony erosion of the sella floor and anterior skull base by the invasive tumour, resulting in the potential development of cerebrospinal fluid (CSF) rhinorrhoea, meningitis, and rarely pneumocephalus. Onset of symptoms is typically within 4 months of commencing therapy. The management is typically surgical repair via an endoscopic transnasal transsphenoidal approach. A 23-year-old man presented to the Emergency Department with acute left limb weakness and intermittent headaches. Visual fields were full to confrontation. Immediate computed tomography and subsequent magnetic resonance imaging (MRI), demonstrated a 5 cm lobular/cystic mass invading the right cavernous sinus, displacing and compressing the midbrain, with destruction of the bony sella. He was referred to the regional pituitary multidisciplinary team (MDT). Serum prolactin was 159 455 mIU/l (7514.37 ng/ml) (normal ranges 100–410 mIU/l (4.72–19.34 ng/ml)). Cabergoline was commenced causing dramatic reduction in tumour size and resolution of neurological symptoms. Further dose titrations were required as the prolactin level plateaued and significant residual tumour remained. After 13 months of treatment, he developed continuous daily rhinorrhea, and on presenting to his general practitioner was referred to an otolaryngologist. When next seen in the routine regional pituitary clinic six-months later he was admitted for urgent surgical repair. Histology confirmed a prolactinoma with a low proliferation index of 2% (Ki-67 antibody). In view of partial cabergoline resistance he completed a course of conventional radiotherapy. Nine months after treatment the serum prolactin had fallen to 621 mIU/l, and 12 months after an MRI showed reduced tumour volume.

Abstract
BACKGROUND Meningitis is an uncommon complication of an untreated pituitary macroadenoma. Meningitis may occur in patients with macroadenomas who have undergone transsphenoidal surgery and radiotherapy and is usually associated with rhinorrhea. Less commonly, cerebrospinal fluid rhinorrhea has been reported as a complication of treatment of prolactinomas by dopamine agonists. Cerebrospinal fluid rhinorrhea in cases of untreated pituitary macroadenoma is reported only in isolated cases. Acute bacterial meningitis without rhinorrhea in patients with an untreated pituitary macroadenoma is an exceptional finding with only three previously reported cases. CASE PRESENTATION A 31-year-old male was urgently admitted for headache, fever and visual loss. Neuroimaging disclosed an invasive pituitary lesion. Cerebrospinal fluid leakage was not clinically detected. Lumbar puncture showed acute meningitis. Blood tests revealed increased inflammatory markers, a serum prolactin of 9000 ng/ml (2.5-11 ng/ml) and panhypopituitarism. Intravenous antibiotics and hydrocortisone replacement therapy were initiated, leading to a favorable clinical outcome. An endoscopic transsphenoidal debulking procedure was performed, it showed that the sphenoid floor was destroyed and the sinus occluded by a massive tumor. CONCLUSIONS Meningitis should be ruled out in patients with a pituitary mass who present with headache and increased inflammatory tests, even in the absence of rhinorrhea.

Abstract
Prolactinomas are the most common type of pituitary adenomas. Macroprolactinomas are the name used for these tumors when their size is ≥ 1 cm. These tumors commonly cause symptoms due to the excessive production of prolactin as well as complaints caused by tumor mass and compression of neural adjacent structures. Clinical diagnosis and assessment of macroprolactinoma are based on the measurement of serum prolactin concentrations and the morphological evaluation of the pituitary gland by magnetic resonance imaging. Dopamine agonists are the first-line treatment modality, with cabergoline being preferred to bromocriptine, because of its better tolerance and feasibility of administration. Cabergoline therapy has been reported to achieve normalization of prolactin levels and gonadal function and reduction of tumor volume in >50% of patients with macroprolactinoma. Resistance or intolerance to dopamine agonists are the main indications for transsphenoidal adenomectomy in patients with macroprolactinoma. External radiation therapy has been used in patients with poor response to medical and surgical procedures. Clinically significant tumor growth may occur during pregnancy in women with macroprolactinomas, especially if they have not received prior surgical or radiation therapy. Visual fields should be assessed periodically during pregnancy and therapy with dopamine agonists is indicated if symptomatic tumor growth occurs. Cystic and giant prolactinomas as well as the rare cases of malignant prolactinomas have special peculiarities and entail a therapeutic challenge.

Abstract
C-type natriuretic peptide (CNP/Nppc) is expressed at high levels in the anterior pituitary of rats and mice and activates guanylyl cyclase B receptors (GC-B/Npr2) to regulate hormone secretion. Mutations in NPR2/Npr2 can cause achondroplasia, GH deficiency, and female infertility, yet the normal expression profile within the anterior pituitary remains to be established in humans. The current study examined the expression profile and transcriptional regulation of NPR2 and GC-B protein in normal human fetal pituitaries, normal adult pituitaries, and human pituitary adenomas using RT-PCR and immunohistochemistry. Transcriptional regulation of human NPR2 promoter constructs was characterized in anterior pituitary cell lines of gonadotroph, somatolactotroph, and corticotroph origin. NPR2 was detected in all human fetal and adult pituitary samples regardless of age or sex, as well as in all adenoma samples examined regardless of tumor origin. GC-B immunoreactivity was variable in normal pituitary, gonadotrophinomas, and somatotrophinomas. Maximal transcriptional regulation of the NPR2 promoter mapped to a region within -214 bp upstream of the start site in all anterior pituitary cell lines examined. Electrophoretic mobility shift assays revealed that this region contains Sp1/Sp3 response elements. These data are the first to show NPR2 expression in normal human fetal and adult pituitaries and adenomatous pituitary tissue and suggest a role for these receptors in both pituitary development and oncogenesis, introducing a new target to manipulate these processes in pituitary adenomas.

Abstract
Treatment of patients with prolactinomas consists primarily of dopamine agonists (DA). When these drugs reduce the size of invasive prolactinomas, the intra- and extra-cranial spaces may be communicated. Pneumocephalus and cerebrospinal fluid leakage have been reported. A 56 year old male was admitted to the emergency unit with an intracranial hypertension syndrome. He had been treated for 2 weeks with cabergoline after an invasive prolactinoma was discovered. Brain CT showed frontal interhemispheric pneumocephalus on the previous tumor cavity, and bony defect on the sellar floor. Evacuation of pneumocephalus, reparation of cranial and meningeal defects and subtotal tumor removal were performed. The literature is reviewed looking for possible pathophysiological mechanism, prevention and treatment.

Abstract
Abstract
BACKGROUND AND OBJECTIVE:
Nonfunctioning and functioning pituitary tumors can present in numerous ways. They may be difficult to diagnose correctly and, even with proper treatment, may lead to complications.
METHODS:
We present the case of a patient who presented with a large, invasive sellar mass and underwent both medical and surgical treatment for this lesion. The patient's course did not progress as was expected from his initial workup.
RESULTS:
The patient's history, physical examination, laboratory values, pathologic specimens, and radiologic findings are discussed. His management before, during, and after medical therapy and surgery is reviewed by pituitary experts from 2 different institutions. Aspects of diagnosis and management of sellar lesions are presented and reviewed in the literature.
CONCLUSION:
Neurosurgeons frequently treat patients with sellar lesions and should remember that despite modern laboratory, pathologic, and radiologic techniques, the diagnosis and treatment of these lesions is not always clear.

Abstract
Hypogonadism in the male results from inadequate testicular function, especially defects in androgen synthesis and secretion, or action. Androgen action is important throughout normal male development: in the fetus, puberty, adult life and old age. Regulation is by variable activity of the hypothalamo-pituitary axis at different phases of the life span. Clinical aspects include: genetic aspects presenting at birth and pubertal failure/arrest. Aspects in adult life embrace sexuality, somatic symptoms and osteoporosis. Acquired causes of hypogonadism may arise from various forms of testicular damage (primary hypogonadism), pituitary and hypothalamic disorders, as well as aetiologies acting at several sites. Measurement of testosterone (T) is crucial to the diagnosis of hypogonadism and the technologies continue to develop, with recent major advances. A growing problem relates to the diagnosis and treatment of hypogonadism in the ageing male. T therapy is available in several forms, with major improvements in more newly available modalities.

Abstract
There have been huge advances in endocrine care as a consequence of improved biochemistry and diagnostic techniques as well as improved imaging. Specialist transethmoidal endoscopic surgery has improved results in pituitary tumour patients and minimally invasive parathyroid surgery has had the same consequence in patients with parathyroid disease. Multidisciplinary teams have improved outcomes in a number of areas and, as described above, endocrinologists are dealing with more in the way of endocrine disease to expand boundaries. Much work remains to be done particularly concerning the care of children and adults with late endocrine effects of cancer treatment and obesity.

Abstract
Although cabergoline is effective in the treatment of micro- and macro-prolactinoma, little is known about its efficacy in the treatment of invasive giant prolactinoma. We investigated the efficacy and safety of cabergoline in 10 male patients with invasive giant prolactinoma. Before treatment, mean serum prolactin level was 11,426 ng/mL (range, 1,450-33,200 ng/mL) and mean maximum tumor diameter was 51 mm (range, 40-77 mm). Three months after initiation of cabergoline treatment, serum prolactin concentrations decreased more than 97% in 9 patients; at last follow-up (mean treatment duration, 19 months), the mean decrease in serum prolactin concentrations was 98%, with 5 patients having normal serum prolactin levels. At first MRI follow-up (3-12 months after initiation of cabergoline), the mean reduction in tumor size was 85+/-4% (range, 57-98%). Cabergoline treatment for more than 12 months caused a greater reduction in tumor size compared to the treatment for less than 12 months (97+/-1% vs. 78+/-7%, P<0.05). These findings indicate that cabergoline treatment led to a significant and rapid reduction in serum prolactin concentrations and tumor size in patients with giant prolactinoma. Therefore, cabergoline represents an effective and well-tolerated treatment for invasive giant prolactinoma.

Abstract
BACKGROUND The frequency of spontaneous CSF rhinorrhea in macroprolactinoma patients is poorly documented and was previously thought to be a very rare occurrence. METHODS Thirty patients with macroprolactinomas (>1.0 cm diameter) identified from the Swansea neuroendocrine database were studied retrospectively. RESULTS At presentation, the median serum prolactin was 28,354 (range, 1844 to >6,000,000) mU/L; radiologically, 4 adenomas were invading the cavernous sinus, one the sphenoid sinus and 5 both the cavernous and sphenoid sinus. After commencement of medical therapy, 4 subjects developed CSF rhinorrhea requiring surgical correction; all 4 had tumors invading both the cavernous and sphenoid sinus and an initial serum prolactin more than 75,000 mU/L. One subject developed an acute psychosis, and a man who presented with delayed puberty committed a serious sexual offense. CONCLUSIONS Serious adverse effects are not uncommon in medically treated macroprolactinoma patients. Subjects with adenomas invading the sphenoid sinus have a high risk of developing CSF rhinorrhea that requires neurosurgical intervention.

Abstract
A 29-year-old male university student, with no prior history of trauma, presented with a 1 year history of clear fluid leaking intermittently from his left nostril. His past medical history included bilateral gynaecomastia since age 12, and recent low libido. β2-transferrin analysis of the nasal fluid confirmed a diagnosis of cerebrospinal fluid (CSF) rhinorrhoea. The serum prolactin was grossly elevated at 42 700 mU/l and brain magnetic resonance imaging (MRI) revealed a large parasellar/sellar mass. A diagnosis of invasive macroprolactinoma complicated by spontaneous CSF rhinorrhoea was made. The patient was commenced on treatment with cabergoline, but while awaiting surgery to repair the CSF leak he developed streptococcus mitis and sanguis meningitis. He made an uncomplicated recovery with antibiotic treatment. Immediately following this episode, the CSF rhinorrhoea resolved spontaneously. Subsequently, a repeat MRI scan revealed dramatic involution of the pituitary mass and the serum prolactin had fallen to 604 mU/l.

Abstract
CONTEXT Macroprolactinomas poorly responsive to dopamine-agonists are often more aggressive and are usually termed 'resistant' but this clinical concept has always been defined empirically. OBJECTIVE To define resistance to cabergoline (CAB) on the basis of a dose-response relationship established in a large series of macroprolactinoma patients and to assess the influence of gender and tumor invasiveness on the response to treatment. DESIGN Retrospective study. METHODS One hundred and twenty-two patients (72 women and 50 men) primarily treated with CAB for at least 1 year were included. Main outcome measures were serum prolactin (PRL) and tumor size. RESULTS Normalization of PRL was obtained in 115 out of the 122 patients (94%). The majority of patients (96/115, 83%) were controlled with a CAB dose < or =1.5 mg/week. Most of the other patients (19/26) had only a partial resistance, responding to a further increase of the CAB dose. Beyond the dose of 3.5 mg/week, there was no clear advantage in further increasing the dose instead of continuing the treatment at the same dose. Most tumors (98/119 assessable cases, 82%) showed a significant shrinkage during CAB treatment. It was more likely to occur in cases of PRL normalization. Both cavernous sinus invasion and male gender were significantly and independently associated with partial or complete resistance to treatment. CONCLUSIONS Most macroprolactinomas primarily treated with CAB are adequately controlled with doses < or =1.5 mg/week. About 20% of patients, mainly men and/or those with invasive tumors will require a higher dose of CAB. We suggest defining such patients as resistant to CAB.

Abstract
OBJECTIVE During dopaminergic agonist treatment for macroprolactinoma, tumour shrinkage can be accompanied by secondary deterioration of the visual field in rare instances. The aim of the present study was to evaluate the incidence of symptomatic or asymptomatic delayed visual loss associated with chiasmal herniation during long-term cabergoline treatment of macroprolactinomas and to report our experience of its management. PATIENTS The study included 28 patients (11 women and 17 men) aged 14-85 years treated for macroprolactinoma with cabergoline at our centre from 1997 to 2006. RESULTS Chiasmal herniation was observed at MRI in five out of the 28 cases. A systematic visual field evaluation revealed visual field worsening, during cabergoline treatment, in three out of these five patients. In two asymptomatic patients, secondary deterioration of visual field occurred 2.5 years and 4 years, respectively, after cabergoline treatment initiation. In the third case, cabergoline treatment resulted in a paradoxical worsening of an initial visual defect. In all three cases, visual fields improved after cabergoline withdrawal although chiasmal herniation persisted. Visual field remained normal in the two other patients. CONCLUSIONS Our results suggested that chiasmal herniation associated with delayed visual field defect is not a rare feature during cabergoline treatment of macroprolactinomas. It should be assessed by systematic visual field evaluation and treated by adaptation of medical treatment.
