BACKGROUND: Turner syndrome (TS) is the most common sex chromosome abnormality in females, typically associated with primary amenorrhea and premature ovarian failure due to gonadal dysgenesis. The association of TS with hypopituitarism is an uncommon finding. The objective of the study was to describe an adolescent with TS with hypergonadotropic hypogonadism and subsequent hypogonadotropic hypogonadism. CASE PRESENTATION: A 16-year-old female with primary amenorrhea was diagnosed with TS based on karyotype 45,XO...

Extract: Dear Editor, Pituitary gigantism is caused by chronic growth hormone (GH) hypersecretion by a pituitary lesion before epiphyseal fusion. Genetic causes have been identified in nearly 50% of patients with pituitary gigantism, with germline mutations in the AIP gene being the most frequent cause (Rostomyan et al. 2015). Recently, a new form of pituitary gigantism, X-linked acrogigantism (X-LAG), was described (Trivellin et al. 2014). X-LAG is due to chromosome Xq26.3 duplication and GPR101 is the disease-associated gene (Trivellin et al...

BACKGROUND: Complete surgical resection of an adrenocorticotropic hormone (ACTH)-secreting pituitary adenoma is the gold standard of treatment of Cushing disease. Ectopic location of these adenomas is an extremely rare condition that may compromise the diagnosis and surgical success. We present the first case of an ectopic intracavernous ACTH-secreting macroadenoma totally resected with endoscopic endonasal surgery (EES). CASE DESCRIPTION: A 36-year-old woman presented with Cushing syndrome...

A 68-year-old female patient was admitted in our clinic with severe frontal bilateral headache, dizziness, depression and cognitive decline in the context of a previously diagnosed acromegaly. She also had high blood pressure, dyslipidemia, secondary diabetes mellitus. Acromegaly was caused by a growth hormone (GH) secreting-pituitary macroadenoma, so a transsphenoidal surgery was performed. The postoperative magnetic resonance imaging (MRI) scan revealed a 20÷22÷25 mm pituitary mass remnant and medical therapy with somatostatin analogues (SSAs) was started...

BACKGROUND: The co-incidence of parasellar aneurysms (IA) and anterior skull base (ASB) lesions, while rare, presents a management challenge. IAs embedded within, or adjacent to, ASB lesions are at risk in the perioperative period, and may have unique presentations, natural histories, and outcomes. The objective of this study was to outline management options and nuances in patients with coexisting IAs and ASB lesions. METHODS: We retrospectively evaluated all patients who presented for management of IAs and ASB lesions from January 2006 to January 2014...

INTRODUCTION: Pituitary disorders during pregnancy are uncommon. The approach should include a close follow-up in order to reduce maternal and fetal risks associated with physiological changes during pregnancy or treatment side effects. MATERIALS AND METHODS: We report a 21-year-old woman with a thyroid-stimulating hormone-secreting pituitary macroadenoma and positive antithyroid antibodies. She was initially treated using transsphenoidal pituitary surgery. The patient relapsed 17-month post-surgery...

BACKGROUND: Patients with hypothalamic-pituitary disorders (HPD) may be of increased risk to develop overweight and obesity, thereby fostering cardiovascular events. However, it remains unclear if patients with pituitary dysfunctions per se have an increased risk of becoming obese. OBJECTIVE: The objective of this study was to evaluate prevalence and to identify possible predictors of overweight and obesity in patients with pituitary dysfunctions. METHODS: A total of 121 out-patients having various causes for HPD were assessed for height and body weight; body mass index (BMI) was calculated and correlated with clinical features...

Pituitary macroadenomas are the most common suprasellar lesions in adults and are typically managed surgically through transsphenoidal resection when symptomatic. Due to their close proximity to the optic chiasm, pituitary macroadenomas often present with signs of bitemporal hemianopsia. Alternatively, these tumors can cause mass effect, thus presenting with signs of elevated intracranial pressure or can present with signs and symptoms of endocrine dysfunction. Here, we discuss a 55-year-old male diagnosed with a non-functioning pituitary macroadenoma (NFPA) based on cranial imaging, ophthalmologic exam, and endocrine evaluation...

Classified as benign central nervous system (CNS) tumors, pituitary adenomas account for 10% of diagnosed intracranial neoplasms. Although surgery is often curative, patients with invasive macroadenomas continue to experience significant morbidity and are prone to tumor recurrence. Given the identification of human brain tumor-initiating cells (TICs) that initiate and maintain tumor growth while promoting disease progression and relapse in multiple CNS tumors, we investigated whether TICs also drive the growth of human pituitary adenomas...

Till date there are no randomized trials to suggest the superiority of intra-operative magnetic resonance imaging (IOMRI) guided trans-sphenoidal pituitary resection over two dimensional fluoroscopic (2D-F) guided resections. We conducted this trial to establish the superiority of IOMRI in pituitary surgery. Primary objective was to compare extent of tumor resection between the two study arms. It was a prospective, randomized, outcome assessor and statistician blinded, two arm (A: IOMRI, n=25 and B: 2D-F, n=25), parallel group clinical trial...

OBJECTIVE: Impaired glycaemic control, characteristic of acromegaly, can be exacerbated by treatment with somatostatin analogues (SSAs), particularly those with multireceptor activity. We present data from the PRIMARYS study on the impact of the SSA lanreotide, associated with tumour volume and hormonal improvements, on glucose and other metabolic parameters in acromegaly. DESIGN: PRIMARYS was a 48-week open-label single-arm phase 3b study of lanreotide autogel 120 mg/4 weeks...

INTRODUCTION: The co-existence of pituitary adenoma and meningioma is extremely rare. It is even rarer in patients with no previous known risk factors for either tumour. Here, we present a case of synchronous non-functioning pituitary adenoma with suprasellar and olfactory groove meningiomas in a patient without previous irradiation. METHODS: The tumours were diagnosed on MRI in the 65-year-old patient who presented with patchy visual deficits. The decision was made to undergo surgery for resection of the suprasellar meningioma and the pituitary adenoma, leaving the small olfactory groove meningioma intact...

: Pituitary adenomas are a common intracranial neoplasm, usually demonstrating a benign phenotype. They can be classified according to pathological, radiological or clinical behaviour as typical, atypical or carcinomas, invasive or noninvasive, and aggressive or nonaggressive. Prolactinomas account for 40-60% of all pituitary adenomas, with dopamine agonists representing the first-line treatment and surgery/radiotherapy reserved for drug intolerance/resistance or in neuro-ophthalmological emergencies...

OBJECTIVE: The inter-rater reliability of the modified Knosp's classification was measured before the analysis. The clinical validity of the parasellar extension grading system was evaluated by investigating the extents of resection and complication rates among the grades in the endoscopic endonasal transsphenoidal surgery (EETS) for pituitary adenomas. METHODS: From November 2008 to August 2015, of the 286 patients who underwent EETS by the senior author, 208 were pituitary adenoma cases (146 non-functioning pituitary adenomas, 10 adrenocorticotropic hormone-secreting adenomas, 31 growth hormone-secreting adenomas, 17 prolactin-secreting adenomas, and 4 thyroid-stimulating hormone-secreting adenomas; 23 microadenomas, 174 macroadenomas, and 11 giant adenomas)...

A 9 year old male mixed-breed dog was presented for progressive aggressiveness towards the owner. The neurological evaluation was consistent with a forebrain syndrome. Magnetic Resonance Imaging (MRI) of the brain revealed enlargement of the third ventricle and presence of a large spheroidal neoplasm in the sellar/parasellar region suggestive of a pituitary macroadenoma. On the owner request, the dog was euthanized. Histopathological examination revealed the presence of a pituitary chromophobe carcinoma. To the author's knowledge, pituitary carcinomas have been rarely described in dogs, especially the chromophobe subtype...

BACKGROUND: The pituitary adenoma causing acromegaly is typically resected through a transsphenoidal approach and visualised with an operating microscope or endoscope. We undertook a systematic review and meta-analysis examining the clinical efficacy of endoscopic and microsurgical approaches. METHODS: Relevant studies using either endoscopic or microscopic transphenoid approaches for growth-hormone pituitary adenomas were identified up to Feb 2016. Data were extracted and analyzed according to predefined clinical endpoints...
