ABSTRACT: Rupture of intracranial aneurysm resulting in subarachnoid hemorrhage is well known to carry significant risk of poor outcome. Intra-operative rupture of an unknown intracranial aneurysm during a neurosurgical procedure is a rare occurrence that can lead to devastating consequences if not recognized and managed appropriately. Here we describe to our knowledge, the first reported case of previously unknown, remote from the surgical site, intra-operative posterior cerebral artery aneurysm rupture during transnasal endoscopic transphenoidal resection of a pituitary macroadenoma, review relevant literature, and discuss strategies to reduce surgical risk and improve patient outcomes.
