title: Pituitary apoplexy manifesting as diffuse subarachnoid hemorrhage.
abstract: A 46-year-old woman presented with hemorrhage from a non-functioning pituitary adenoma manifesting as sudden onset of severe headache. Computed tomography demonstrated diffuse subarachnoid hemorrhage (SAH) and a suprasellar mass with intratumoral hematoma. The patient underwent transnasal transsphenoidal removal of the pituitary adenoma. This type of SAH with intratumoral hematoma simulates rupture of an anterior cerebral artery aneurysm.
