A 75-year-old lady presented with sudden severe headache and vomiting. Examination was normal, and CT and lumbar puncture not convincing for subarachnoid haemorrhage. Shortly thereafter, she developed painless diplopia. Examination confirmed right third cranial nerve palsy plus homonymous left inferior quadrantanopia. Urgent cerebral MRI with angiography was requested to assess for a possible p...

Occlusion of intracranial arteries by a pituitary adenoma with ensuing infarction is a rare occurrence. In this case study, we show the instance of a pituitary macroadenoma and apoplexy causing mechanical obstruction of the internal carotid artery with consequent infarction following transphenoidal surgery (TSS) and radiation therapy in a patient with Cushing's disease. We report a 44-year-old ...

OBJECTIVE The prognosis of either pituitary carcinoma or aggressive pituitary adenoma resistant to standard therapies is poor. We assessed the efficacy of treatment with temozolomide, an oral second-generation alkylating agent, in a consecutive series of six patients with aggressive pituitary adenomas. DESIGN This was a 1-year prospective study of temozolomide therapy in six consecutive patie...

OBJECTIVE To describe the work-up and treatment of rare ectopic acromegaly caused by a biopsy-proven somatotroph pituitary adenoma located within the bony intersphenoid septum of a patient with empty sella syndrome (ESS). METHODS We report the presentation, clinical course, diagnostic work-up, and lesion localization and treatment challenges encountered in a 55-year-old patient, with a brief ...

(SHBG): 73 nmol/l (normal, 13 to 71). His serum testosterone and the cortisol response on cosyntropin stimulation testing were normal. A presumptive diagnosis of a thyrotropin and growth hormone co-secreting pituitary adenoma was made. Octreotide LAR therapy was advised preoperatively to control thyroid hormone excess. He underwent transsphenoidal resection of the sellar mass, which was consist...

The aim of this study was to examine the secondary visual cortex functional disorder in patients with glaucoma and large pituitary adenoma by functional magnetic resonance imaging, and to determine the correlation between visual field defect and primary visual cortex activation. Results showed that single eye stimulation resulted in bilateral visual cortex activation in patients with glaucoma o...

Sellar tumors are approximately 10-15% among all intracranial neoplasms. The most common sellar lesion is the pituitary adenoma. Manual segmentation is a time-consuming process that can be shortened by using adequate algorithms. In this contribution, we present a segmentation method for pituitary adenoma. The method is based on an algorithm we developed recently in previous work where the novel...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013202041 DESCRIPTION A healthy 68-year-old man presented in the emergency room with a sudden episode of headache and vomiting together with disequilibrium and crural paresis. The laboratory evaluation revealed hyponatraemia (Na+115 mEq/L). Head MRI demonstrated a giant 40×...

Pituitary adenomas represent a group of functionally diverse neoplasms with relatively high prevalence in the general population. Most occur sporadically, but inherited genetic predisposing factors are increasingly recognized. Familial isolated pituitary adenoma is a recently defined clinical entity, and is characterized by hereditary presentation of pituitary adenomas in the absence of clinica...
