新生児Optic gliomaの2例

Optic Glioma in Neonates: Report of two cases

I．はじめに

　新生児期に発症する脳腫瘍は，先天性の色彩が濃く，性格についてもいまだ一致した見解を見出していないが，小児脳神経外科学，小児神経学の発達およびCTscanの普及に伴って，近年次第に報告例が増加している．しかし脳腫瘍全体の中に占める割合は，現在のところ例外的といえるほど少ない^5,6,13）．最近著者らはそのなかでも稀と考えられる生後2カ月以内の新生児期に発症したoptic gliomaの2症例を経験したので，若干の文献的考察を加えて報告する．

We report two cases of optic glioma in neonates, which is rare and onl 3 similar cases can he found in the literature so far.

Case # 1 was a 55-day-old boy having been lethargic since around his 25th postnatal day. Case # 2 was a 100-day-old girl having also been in the same condition as Case # 1 since around her 50th postnatal day. The tumor in either patients seemed to have originated from chiasm or its vicinity and were too large to remove totally.
