The coexistence of cerebral aneurysm and pituitary adenoma has been described previously. Most of such cases harbor functional tumors and anterior circulation aneurysms, with very rare cases of posterior circulation aneurysms. In this report, we present a case of subarachnoidal hemorrhage due to rupture of an undetected basilar apex aneurysm during microscopic transsphenoidal surgery for a nonf...

Lymphocytic hypophysitis may involve the pituitary gland and various hormonal abnormalities. A 72-year-old man presented with euvolemic hyponatremia caused by glucocorticoid deficiency. After glucocorticoid replacement, hypernatremia in the presence of dilute urine was found. Central diabetes insipidus (DI) was confirmed later by a significant increase in urine osmolality after vasopressin admi...

A 39-year-old male without any significant complaints or symptoms presented with a calcified lesion located at the sellar region. Total removal of the lesion has been achieved via an endoscopic endonasal transsphenoidal approach. Histopathological examination of the lesion revealed a pituitary stone. This report describes the first pituitary stone formed within a plurihormonal pituitary adenoma...

The preoperative hypocycloidal sellar tomograms, angiograms, and pneumoencephalograms of 100 patients being evaluated for prolactin-secreting pituitary adenomas were reviewed and the results correlated with surgical findings at transsphenoidal exploration. The majority (53%) of tumors encountered were microadenomas. Although sellar volume was normal in 72%, sellar shape on tomography was abnorm...
