Glioblastoma Presenting as Spontaneous Subarachnoid Hemorrhage: Technical Case Note of Combined Endovascular and Microsurgical Vision-Sparing Treatment.

Abstract

Clinical utility of endovascular adjunct for tumor resection is well established, but its role in acute subarachnoid hemorrhage secondary to neoplastic pseudoaneurysm rupture has not been reported. We discuss a 46-year-old patient presenting with a World Federation of Neurological Surgeons grade 1 subarachnoid hemorrhage from a ruptured posterior cerebral artery pseudoaneurysm due to glioblastoma tumor invasion. A combined targeted endovascular embolization with microsurgical resection to spare the calcarine artery was used to avoid disruption to the optic radiation fiber pathway.
