小児の巨大な髄膜腫の1例

REPORT OF A CASE OF A HUGE SPHENOID RIDGE MENINGIOMA IN A BOY

I．はじめに

　髄膜腫は，一般に良性脳腫瘍の中では最も多いが，小児においては比較的少なく，特に，蝶形骨縁のそれは，小児においては，きわめてまれである。

　われわれは，小児の蝶形骨縁髄膜腫で，しかもその重量が400gを越える巨大な髄膜腫の全摘例に成功したのでここに報告し，従来報告されている巨大な髄膜腫について文献的考察を加えてみたいと思う。

An eight-year-old boy developed vomiting, hemi-apresis on the left side and blurring of vision in a short duration.

Large intracranial tumor at the right temporal area was discovered by carotid angiography. On the craniotomy, the tumor was sphenoid ridge meningi-oma of the clinoidal type which was completely removed in two stages. Postoperative recovery was retarded but satisfactory.

The weight of the tumor was 402 gin. which may be the heaviest one ever reported in children.
