巨大視神経膠腫の1治験例

Giant Optic Glioma:Case Report

Ⅰ．はじめに

　視神経膠腫は比較的まれな腫瘍である．われわれは，直径10cm，重量170gにもおよぶ巨大な視神経膠腫の症例に遭遇し，その全剔出に成功したので，若干の考察を加え報告する．

A 3【1/2】-year-old girl with a huge optic glioma was reported. On February 26, 1978, she was hospitalized for signs of increased intracranial pressure, namely headache, vomiting and consciousness disturbance. Before admission she did not complain of her visual disturbance. A huge mass lesion in the subfrontal-suprasellar region was found by neuroradiological examination. The operation was performed on March 7, 1978, and the tumorarising from the right optic nerve, about 170 grams in weight, was totally removed in piecemeals. Histopathological diagnosis was pilocytic astrocytoma.
