Abstract
Primary intracerebral tumors occasionally present with spontaeous intratumoral hemorrhage, or rarely, spontaneous subarachoid hemorrhage (SAH) [1]. SAH associated with primary brain umors usually results from extension of an intratumoral hemrrhage into the subarachnoid space. Tumors that spread within he distal vasculature (e.g. choriocarcinomas and atrial myxomas) re associated with aneurymsal subarachnoid hemorrhage [1]. owever, the association of a primary intracranial tumor and an djacent intracranial aneurysm is rare, except in the setting of ituitary adenomas. The authors describe a patient who suffered ultiple aneurysmal SAHs during the multimodality treatment f a hypothalamic glioma and concomitant arteriovenous malforation. We suspect that new aneurysm development may have een related to the combination of the peri-tumoral vascular nvironment with the application of anti-angiogenesis therapy, hemotherapy, and stereotactic radiosurgery.
