Encephaloceleを伴った後頭部奇形腫の1例

Occipital Teratoma Associated with Encephalocele

Ⅰ．はじめに

　小児科学，小児脳神経外科学の発達とともに，以前には生下時まもなく死亡し，剖検によって明らかにされたような新生児の奇形性疾患も脳神経外科的治療の対象となる機会が益々増加の傾向をたどりつつある．

　私共は後頭部に一見encephaloceleを思わせる巨大な腫瘤をもって誕生した男児で，encephaloceleと共に奇形腫の存在することを診断し，手術を行ない，その後元気に発育している症例を経験したので報告し，併せて文献的考察を試みる．

A 3-month-old boy, who had been noticed by his parents to have a large tumor in the occipital region since birth, was admitted to Osaka University Hospital Neurosurgical Service for surgery on 6 February 1973.

His face was asymmetrical; right side of the face was underdeveloped. The light reflexes of the pupils were sluggish and his vision was thought to be almost zero. While the upper part of the occipital tumor was soft, the lower part elastic firm. Also in the right temporal region, a soft tumor was present.
