Choi, D S; Ahn, J D

Abstract

A 64 year-old woman was transferred from the psychiatry department to the nenrosurgery on Mar. 1974. Herprincipal complaints were long standing headache, frequent grandmal seizure and episodic dysarthria. The presentillness began in Dec. 1969. about 6 years before admission, with severe headache radiating from the occipitalregion to the temporal and facial region, drowsy mentallity and bilateral papilledema. Examination of the visualfields showed 3 diopters papilledema and no visual disturbance. The plain skull films revealed a hen egg-sizedcloudy, partly denser, and partly starand-like calcific mass in the left frontal lobe area. Left carotid angiogramrevealed smooth rightward displacement toward the affected side of the anterior cerebral artery and lateral anddownward displacement of the knee portion of the middle cerebral artery. Lateral view showed slight downwarddepression of the anterior portion of the sylvian triangle and of the anterior cerebral artery. There was no tumorstaining. Conray ventricuogram showed collapse of the anterior horn of the lateral ventricle and rightwarddisplacement of the 3rd ventricle and septum pellicidum in A-P view. Lateral film showed depression of theanterior horn with nodular filling defects along the lateral ventricle. The tumor was removed radically and thepatholgoy turned out to be oligodendroglioma.
