Background: Craniopharyngioma is a rare epithelial tumor of the central nervous system, affecting both children and adults and associated with significant morbidity.Objective: To study the postsurgical evolution of craniopharyngioma in adults after total or incomplete surgical resection.Material and methods: We performed a retrospective review of craniopharyngioma patients evaluated in the National Institute of Endocrinology in Buc...

Introduction: The most common cause of Cushing’s disease is ACTH secreting tumours of the pituitary gland. It is associated with high morbidity and mortality. Pasireotide, a potential therapy, has a unique, broad somatostatin-receptor–binding profile, with high binding affinity for somatostatin-receptor subtype 5.Case report: We present the a 40-years-old man diagnosed in 2005 with Cushing’s Disease for which a left adrenalectomy was perfo...

Background: A large spectrum of AIP gene mutations has been identified in familial and sporadic pituitary adenomas (PA) with over 70 different mutations described to date. c.47G>A, p.R16H is an AIP exon 1 variant of unknown significance, its contribution to pituitary adenoma development being controversial.Aim: Characterization of p.R16H prevalence in a large Romanian cohort of PA patients and controls.Patients and methods: spo...

Introduction: Monoclonality of pituitary adenomas is an established fact. Still, there are exceptions and polyclonality may correlate with aggressive tumor behavior. In order to test association of clonality with pituitary adenoma characteristics in a series from Romania, we implemented a protocol for X-chromosome inactivation analysis at the androgen receptor (AR) locus (HUMARA) and validated it in a number of tumor samples.Objective: To establish and v...

Background: Thermoregulatory disorders after neurosurgery of craniopharingyomas were seldom reported.Aim: To present the difficulties of etiologic diagnosis and treatment of a persistent febrile syndrome in a patient with surgically removed craniopharyngioma.Patient and methods: A 34 years old man with a giant craniopharyngioma situated in the basal-anterior part of the third ventricle is reported. Anterior pituitary hormones were ...

At least one fifth of pituitary adenomas exhibit plurihormonality when using immunohistochemistry for anterior pituitary hormones. However, the correlation with clinical features is weak, without an agreement upon pathological predictors of tumour behaviour.The aim was to determine the immunoreactivity for anterior pituitary hormones and alpha subunit in 276 consecutive pituitary adenoma patients, aged 22–79 years (44.3±8), 154 F/ 122 M: 83 acr...

IntroductionPituitary apoplexy is a rare entity characterized by abrupt hemorrhage and/or ischaemia of the constituents of sella turcica. It usually occurs in a previously unsuspected pituitary tumor. It may have an acute or subclinical presentation and it may represent a neuroendocrinological emergency.AimThis study aims to analyze predisposing or precipitating factors, clinical status, imaging and hormonal ...

Case presentation: Mrs. S presented in an endocrine clinic for fatigue, weight loss, restlessness and goiter. She was obese with a BMI of 51 kg/mp, hypertensive and had a medium size, nontender goiter. Lab test revealed hyperglycaemia, suppressed TSH (<0.03mUI/L), on two separate occasions, mid-normal fT4 and T3. Thyroid ultrasound revealed multinodular goiter. A diagnosis of polynodular goiter with subclinical hyperthyroidism was made and patient was commenced on thiamazo...

Background: Prolactinoma is the most frequent pituitary tumour. However, peculiar aspects may induce difficulties in their evolution and management. Malignant prolactinoma is exceptionally rare and it cannot be diagnosed on histological grounds alone. We report the case of a recurrent, possibly malignant macroprolactinoma.Case report: 46 years old female, addressed for bitemporal hemianopia, without other clinical signs. MRI confirmed a pituitary macroad...

Introduction: SOX2 is an early developmental transcription factor and a marker for pituitary progenitor cells.The study aimed to investigate if the pituitary adenomas with positive SOX2 immunoreactivity shows a different response to therapy as compared with controls.Patients and methods: We investigated 15 pituitary macroadenomas, eight with SOX2 immunoreactivity (SOX2+) and seven without (SOX2−) (controls); five were GH prod...
