[PMID: 34925240 PMCID: PMC8679660 DOI: 10.3389/fendo.2021.778839] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2021] [Accepted: 11/05/2021] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Transcranial sonography (TCS) is a convenient tool for detecting certain brain diseases, such as brain tumors. Few studies have reported on the use of TCS in the area of Sella turcica. The accuracy and repeatability of Sella turcica with or without pituitary tumor is not clear. PURPOSE This study aimed to investigate the feasibility and accuracy of TCS to measure the size of Sella turcica according to the measurement in MRI and determine its diagnostic performance in individuals with pituitary tumor. MATERIALS AND METHODS In this cross-sectional comparative study, healthy volunteers and patients with pituitary tumor were enrolled for examination of TCS and MRI between October 2020 and July 2021. The transverse diameter (D1, cm) of Sella turcica and the volume of the pituitary tumor were measured by TCS and MRI, respectively, and compared by using Student's t-test or Mann-Whitney test, using the receiver operating characteristic (ROC) curve to analyze the diagnostic value of D1 in TCS for pituitary tumor. RESULTS A total of 75 healthy volunteers and 51 patients with pituitary tumor were evaluated. In healthy volunteers, the mean D1 was 1.30 ± 0.35 (range, 0.82-3.22) by TCS and 1.32 ± 0.29 (range, 0.94-3.02) by MRI (P = 0.054). In patients with pituitary tumor, the mean D1 was 2.0 ± 0.65 (range, 0.90-3.48) by TCS and 2.42 ± 1.0 (range, 0.80-4.70) by MRI (P = 0.000). The median measurement volume was 4.41 and 6.59 cm3 in TCS and MR, respectively (P = 0.000). The mean D1 was 1.31 ± 0.35 in healthy volunteers and 2.0 ± 0.65 cm in patients with pituitary tumor (P = 0.000). In the ROC curve analysis, the area under the curve was 0.836, and the optimal cutoff value (1.56) exhibited a sensitivity and specificity of 67.31 and 88.0%, respectively. CONCLUSION The consistency between the two imaging technologies performed well in D1 measurement, while the volume of the pituitary tumor was smaller as assessed by TCS than by MRI. D1 in TCS had good diagnostic performance in pituitary tumor.

Abstract
Idiopathic Intracranial Hypertension is a neurological disorder primarily affecting overweight women of childbearing age. It is often characterized by radiologic evidence of empty sella (ES), which is in turn frequently associated with pituitary dysfunction, with the somatotropic axis most commonly affected. No recent evidence is available relative to the presence of pituitary hormone deficiencies in adult patients with Idiopathic Intracranial Hypertension (IIH) under pharmacological therapy. We therefore explored pituitary function and morphology in a small cohort of female patients with IIH treated with acetazolamide. Fifteen female patients aged 42 ± 13 years with IIH lasting between 12 and 18 months were evaluated. All patients were affected by recurrent headaches in addition to visual changes of variable severity. IIH diagnosis was made after exclusion of other causes of raised intracranial pressure, and a specific ophthalmological evaluation was conducted to assess for the presence of papilledema. No particular endocrinological disturbances were detected during the enrolment visits, except for a high obesity prevalence (87%, BMI 35.16 ± 8.21 kg/m2), one case of total thyroidectomy for papillary thyroid carcinoma and two patients with irregular menses and mild hirsutism. All the participants underwent a pituitary MRI with contrast, and two different operators performed pituitary measurements in coronal and sagittal scans for morphologic assessment. Blood samples for the anterior pituitary axis evaluation were collected, and the somatotropic axis was further evaluated with a GHRH + Arginine test; other dynamic tests were performed in case of suspected hormonal deficiency. Despite ES being found in 73% of the patients, pituitary volume was preserved, ranging from 213.85 to 642.27mm3 (389.20 ± 125.53mm3); mean coronal pituitary height was 4.53 ± 1.33 mm. Overall, baseline anterior pituitary hormones levels were within normal ranges, and none of the patients with ES had an altered response to the GHRH + arginine stimulation test. We found one patient suffering from iatrogenic hyperthyroidism and two diagnosed with subclinical primary hypothyroidism due to Hashimoto's thyroiditis. Two young patients were suspected of having polycystic ovary syndrome, and they were therefore further investigated. In conclusion, this case series shows that, despite the high prevalence of ES, the pituitary function of IIH patients treated with acetazolamide is preserved. To date, there is no evidence regarding the trend over time or upon treatment discontinuation in regard to the pituitary function of patients with IIH, and it is therefore not possible to infer whether our finding would be replicable in such settings. We therefore suggest an endocrine follow-up over time in order to monitor for potential pituitary dysfunction.

Abstract
Background Endoscopic endonasal repair of cerebrospinal fluid (CSF) rhinorrhea secondary to idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri or benign intracranial hypertension, has varying success rates, from 25–87%, with minimal morbidity. However, often these series have a relatively short-term follow-up. Given the pathophysiology of IIH, long-term follow-up is necessary to identify true CSF leak recurrence rates. Our investigation aimed to evaluate long-term outcomes in endoscopically repaired CSF leaks. Methods A retrospective chart review of all the patients with CSF rhinorrhea due to IIH who met inclusion criteria between 1996 and 2009. Outcome measures included the following: demographics, intracranial pressure, location of skull base defect, presence of encephalocele and/or meningoencephalocele, surgical repair technique, treatment with acetazolamide, whether a ventriculoperitoneal shunt was inserted, location of recurrence, history of meningitis or previous sinus surgery, and duration of follow-up. Results Thirty-two patients with a total of 44 skull base defects were reviewed over a mean follow-up of 10.2 years. The mean body mass index and intracranial pressure were 36.8 kg/m2 and 27.7 cm H2O, respectively. Seven patients (18%) required revision surgery at the same site or a distant site. We found no statistical significance that identified the recurrence risk in the outcome measurements most likely due to our small failure rate. However, early recurrences were noted to recur at the same repair site, whereas late recurrences were noted to recur at a distant site along the skull base. Conclusion IIH is an increasingly recognized entity treated by otorhinolaryngologists. We present the first long-term IIH CSF leak repair series. Long-term follow-up is necessary because delayed CSF leaks occur in this population.

Pseudotumor Cerebri in a Child with Idiopathic Growth Hormone Insufficiency Two Months after Initiation of Recombinant Human Growth Hormone Treatment. Case Rep Ophthalmol Med 2016; 2016:4756894.

Abstract
Purpose. To report a rare case of pseudotumor cerebri (PTC) in a child two months after receiving treatment with recombinant human growth hormone (rhGH) and to emphasize the need of close collaboration between ophthalmologists and pediatric endocrinologists in monitoring children receiving rhGH. Methods. A 12-year-old boy with congenital hypothyroidism started treatment with rhGH on a dose of 1,5 mg/daily IM (4.5 IU daily). Eight weeks later, he was complaining of severe headache without any other accompanying symptoms. The child was further investigated with computed tomography scan and lumbar puncture. Results. Computed tomography scan showed normal ventricular size and lumbar puncture revealed an elevated opening pressure of 360 mm H2O. RhGH was discontinued and acetazolamide 250 mg per os twice daily was initiated. Eight weeks later, the papilledema was resolved. Conclusions. There appears to be a causal relationship between the initiation of treatment with rhGH and the development of PTC. All children receiving rhGH should have a complete ophthalmological examination if they report headache or visual disturbances shortly after the treatment. Discontinuation of rhGH and initiation of treatment with acetazolamide may be needed and regular follow-up examinations by an ophthalmologist should be recommended.

Abstract
INTRODUCTION Empty sella in MRI is an important finding associated with idiopathic intracranial hypertension (IIH). This study assesses the sensitivity and reproducibility of several morphological measures of the sella and pituitary gland to indentify the measure that best differentiates IIH from controls. Additionally, the study assesses reversal in gland compression following treatment. METHODS Sagittal 3D-T1W sequence with 1 mm isotropic resolution was obtained from ten newly diagnosed IIH patients and 11 matched healthy controls. Follow-up MRI scans were obtained from eight patients at 1-week post-lumbar puncture and acetazolamide treatment. 1D and 2D measures of absolute and normalized heights and cross-sectional areas of the gland and sella were obtained to identify the measure that best differentiates IIH patients and controls. RESULTS Overall area-based measurements had higher sensitivity than length with p < 0.0001 for sella area compared with p = 0.004 for normalized gland height. The gland cross-sectional areas were similar in both cohorts (p = 0.557), while the sella area was significantly larger in IIH, 200 ± 24 versus 124 ± 25 mm(2), with the highest sensitivity and specificity, 100% and 90.9%, respectively. Absolute gland area was the most sensitive measure for assessing post treatment changes, with 100% sensitivity and 50 % specificity. Average post-treatment gland area was 18% larger (p = 0.016). Yet, all eight patients remained within the empty sella range based on a normalized gland area threshold of 0.41. CONCLUSIONS Sellar area is larger in IIH, and it demonstrated highest sensitivity for differentiating IIH from control subjects, while absolute gland area was more sensitive for detecting post treatment changes.

Abstract
A 9-year-old girl, treated for growth hormone deficiency, developed bitemporal progressive headache, diplopia, acute comitant esotropia and visual loss 3 months after starting recombinant growth hormone. An increased intracranial pressure was revealed by examination of ocular fundus and lumbar puncture, and the absence of other causes, ruled out through a brain scan, led to the diagnosis of idiopathic intracranial hypertension. Recombinant growth hormone was discontinued and acetazolamide started up to 30 mg/kg/die without any clinical improvement but developing metabolic acidosis. The switch to intravenous dexamethasone (0.4 mg/kg/die) led to a dramatic clinical improvement after only 1 day, then confirmed by examination of ocular fundus and visual evoked potentials. Currently, there are no evidence-based guidelines for the management of intracranial hypertension, and even though acetazolamide is recognized as the first-line drug, its efficacy and safety have not been proven: some patients might not respond and others will present unacceptable side-effects. Therefore we suggest the use of corticosteroids in intracranial hypertension when acetazolamide is inefficient or intolerable.

Abstract
Our understanding of pediatric idiopathic intracranial hypertension has been refined since Dr. Simmons Lessell's review in 1992. The use of rigorous methodologies and standard definitions in recent studies has demonstrated distinct demographic trends. Specifically, the incidence of idiopathic intracranial hypertension seems to be increasing among adolescent children, and among older children its clinical picture is similar to that of adult idiopathic intracranial hypertension (female and obese). Within younger age groups there are more boys and nonobese children who may develop idiopathic intracranial hypertension. The pathogenesis of the disease has yet to be elucidated. Idiopathic intracranial hypertension among young children has been associated with several new etiologies, including recombinant growth hormone and all-trans-retinoic acid. More modern neuroimaging techniques such as MRI and MRI-venograms are being used to exclude intracranial processes. Although most cases of pediatric idiopathic intracranial hypertension improve with medical treatment, those who have had visual progression despite medical treatment have undergone optic nerve sheath fenestration and lumboperitoneal shunting. Because idiopathic intracranial hypertension in young children appears to be a different disorder than in adolescents and adults, separate diagnostic criteria for younger children are warranted. We propose new criteria for pediatric idiopathic intracranial hypertension in which children should have signs or symptoms consistent with elevated intracranial pressure, be prepubertal, have normal sensorium, can have reversible cranial nerve palsies, and have an opening cerebrospinal fluid pressure greater than 180 mm H(2)O if less than age 8 and papilledema is present, but greater than 250 mm H(2)0 if age 8 or above or less than 8 without papilledema.

Abstract
BACKGROUND Several uncommon adverse effects may be related to growth hormone (GH) treatment. Three potential side effects, headache, idiopathic intracranial hypertension (IIH) and slipped capital femoral epiphysis (SCFE), will be discussed. Data from 57,968 children in the KIGS (Pfizer International Growth Study database) were analyzed to determine the effects of recombinant human GH (Genotropin) on these side effects. The diagnostic groups were idiopathic GH deficiency (IGHD) (n = 27,690), congenital GHD (CGHD) (n = 2,547), craniopharyngioma (n = 1,155), cranial tumours (n = 2,203), Turner syndrome (TS) (n = 6,092), idiopathic short stature (ISS) (n = 5,286), small for gestational age (SGA) (n = 2,973), chronic renal insufficiency (CRI) (n = 1,753) and Prader-Willi syndrome (PWS) (n = 1,368). RESULTS Total incidence (per 100,000 treatment years) of headache was 793.5 (n = 569). The incidence was significantly higher in the groups of patients with craniopharyngiomas, CGHD and cranial tumours than in the other diagnostic groups (p < 0.05 for all). IIH occurred in 41 children resulting in a total incidence (per 100,000 treatment years) of 27.7. The incidence (per 100,000 treatment years) was significantly lower in patients with IGHD (12.2) than in those with TS (56.4) (p = 0.0004), CGHD (54.5) (p = 0.0064), PWS (68.3) (p = 0.0263) and CRI (147.8) (p < 0.001). No cases of IIH were reported in the ISS group of patients. The median duration from onset of GH therapy to IIH ranged from 0.01 to 1.3 years in various diagnostic groups. SCFE was observed in a total of 52 children resulting in a total incidence (per 100,000 treatment years) of 73.4. The incidence (per 100,000 treatment years) was significantly lower in patients with IGHD (18.3) and in those children with ISS (14.5) than in the TS (84.5), cranial tumours (86.1) and craniopharyngioma groups (120.5) (p < 0.05 for all). No cases of SCFE were reported in the SGA and PWS groups. The median duration from onset of GH therapy to SCFE ranged from 0.4 to 2.5 years. CONCLUSIONS The incidences of IIH and SCFE in this analysis are lower than the values reported in previous KIGS analyses and comparable to other databases. Patients with TS, organic GHD, PWS and CRI seem to be more prone to these side effects.

Abstract
Idiopathic intracranial hypertension (IIH) is the syndrome of raised intracranial pressure without clinical, laboratory or radiological evidence of intracranial pathology. IIH is a relatively rare disease but rapidly increasing incidence is reported due to a global increasing incidence of obesity. Disease course is generally said to be self-limiting within a few months. However, some patients experience a disabling condition of chronic severe headache and visual disturbances for years that limit their capacity to work. Permanent visual defects are serious and not infrequent complications. The pathophysiology of IIH is still not fully understood. Advances in neuroimaging techniques have facilitated the exclusion of associated conditions that may mimic IIH. No causal treatment is yet known for IIH and existing treatment is symptomatic and rarely sufficient. The aim of this review is to provide an updated overview of this potentially disabling disease which may show a future escalating incidence due to obesity. Theories of pathogenesis, diagnostic criteria and treatment strategies are discussed.

Abstract
Pseudotumor cerebri is a perplexing syndrome of increased intra-cranial pressure without a space-occupying lesion. The terminology for the disorder has changed over the years and the diagnostic criteria revised to reflect advances in diagnostic technology and insights into the disease process. The classification and nomenclature depend on the presence or absence of an underlying cause. When the diagnostic criteria are followed, a secondary etiology is unlikely. When no secondary cause is identified, the syndrome is termed "idiopathic intracranial hypertension."

Abstract
We studied prospectively the etiology, clinical presentation, and outcome of idiopathic intracranial hypertension in 36 patients (20 boys and 16 girls) aged 3.5 months to 14 years. The etiology was identified in 28 (77.7%) patients. The most common predisposing factor was middle-ear infection, followed by obesity. Of the 36 cases seen, 26 presented with the classic picture of headaches, papilledema, and elevated cerebrospinal fluid pressure; 8 children had intracranial hypertension in the absence of papilledema and 2 had fundoscopic evidence of papilledema with normal cerebrospinal fluid pressure initially. In four children resolution of intracranial hypertension occurred with removal of the causative agent or appropriate treatment of the underlying condition. In 8 of 17 patients intracranial hypertension resolved with acetazolamide therapy and in 22 of 24 patients it resolved with corticosteroids in combination with acetazolamide. Subnormal visual acuity, narrowing of visual fields, or both were present on the initial examination in 10 patients; 2 of them, who presented with loss of vision, have permanent visual impairment. Four additional patients presented a transient, mild impairment of visual acuity during treatment. Our study confirms the wide clinical spectrum and the difficulties encountered in diagnosis of idiopathic intracranial hypertension. A wide variety of etiologic associations should be investigated to provide definitive therapy. Loss of visual function is the only serious complication.

Abstract
PURPOSE This article represents the first report in the ophthalmology literature of an association between pseudotumor cerebri (PTC) and recombinant human growth hormone (rhGH). DESIGN Noncomparative case series. PARTICIPANTS Three children receiving rhGH for short stature with Turner syndrome, Jeune syndrome, or Down syndrome. METHODS Children underwent full ocular examination. After papilledema was identified, patients underwent lumbar puncture and imaging with either magnetic resonance imaging or computerized tomography. Treatment was under the guidance of the primary physician or neurosurgeon. The rhGH was discontinued in all children. MAIN OUTCOME MEASURES Visual acuity and evaluation of the optic nerve for resolution of papilledema were followed at each examination. RESULTS In all three cases, papilledema resolved with the cessation of rhGH, and treatment with acetazolamide or prednisone. Visual acuity was unchanged in case 1, decreased by two to three lines in case 2, and was inconsistent in case 3. One child (case 2) required a ventriculoperitoneal shunt for persistent elevation of intracranial pressure. CONCLUSION There appears to be a causal relationship between the initiation of rhGH with the development of PTC. Children should have a complete ophthalmic evaluation if they report headache or visual disturbances. Baseline examination with routine follow-up should be instituted when children cannot adequately communicate.
