脳動脈瘤術後にくも膜下出血をおこした脳腫瘍の一例

A CASE OF ANOTHER SUBARACHNOID HEMORRHAGE FROM BRAIN TUMOR AFTER OPERATIVE OCCULUSION OF INTRACRANIAL ANEURYSM

I．緒言

　脳腫瘍が大量のくも膜下出血をおこすことは比較的稀なことである^2）。われわれは，脳動脈瘤の術後にも，くも膜下出血をおこした脳腫瘍症例を経験したので報告する。

A case of 42 years old male was presented who suffered from repeated subarachnoid hemorrhage initially resulted from a ruptured aneurysm of the anterior communicating artery and later from a glioblastoma multiforme of the bilateral frontal lobes.

First attack occured with drowsiness and severe headache, and an anterior communicating aneurysm was successfully clipped five months later. The post-operative recovery had been uneventful. Two months later there was second episode of a subarach-noid bleeding with drowsiness, stiffneck and 1- hemiparesis. At this time, bilateral frontal mass lesion was apparent on carotid angiography and unexpectedly a glioblastoma multiforme containing hemorrhagic lesions was removed.

Another subarachnoid bleeding following com-plete operative occulsion of aneurysm is rare, but possibility of other lesion causing hemorrhage such as tumor must be considered.
