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

Background: 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. Case Description: 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. Conclusions: A combined targeted endovascular embolization with microsurgical resection to spare the calcarine artery was used to avoid disruption to the optic radiation fiber pathway.
