原発性視神経Gliomaの2例

Primary Glioma of the Optic Nerve : Report of two Cases

I．緒言

　原発性視神経gliomaは比較的稀な疾患とされ，我国に於いては，22例の報告を見るに過ぎない。今回，著者は，本症2例に遭遇し，臨床的並びに病理組織学的検索を行つたのでここに報告する。

A description is made over the occurrence of glioma of the optic nerve in a 7-year-old boy and a 5-year-old girl. In both cases the cardinal symptoms consisted of unilateral exo-phthalmos and loss of visual acuity. Histolo-gical examinations after successful removal of the eyeball and the tumor proved the glio-ma to be astrocytomas. In spite of radiogra-phically discernible enlargement of the optic canal in both cases there were no features indicative of recurrences duning the postope-rative observation period of 3 years and 1 year respectively.
