透明中隔腔嚢包の3例

THREE CASES OF CYST OF CAVUM SEPTI PELLUCIDI

I．緒言

　透明中隔腔ならびにVerga氏腔嚢包に関する報告は1851年におけるAndrea Verga^1）の剖検例が最初だといわれている。しかし，気脳写によつて確かめられたのは比較的新しく，1930年のErnst Meyer^2）が最初であり，以来欧米では60余例の報告があるとされている。本邦においては1931年の内村^3）の報告が最初であるが，その後の症例と合わせてもわずか10例をみるにすぎない。それらのあるものは，脳腫瘍類似の症状を呈してはいるが，反面，全然無症状のものもあり，本症の診断や治療法などに関して一定の見解を得るまでにはいたつていない。したがつて，まず症例を積むことが先決の問題と考えられるが，われわれも気脳写ならびにヨード油脳室撮影によつて透明中隔腔ならびにVerga氏腔嚢包と考えられる3例を経験したので報告したい。

Cyst of Cavum septi pellucide was disco-vered in three patients, 36 year-old, 14 year-old male, and 6 year-old female.

In the first patient, who have suffered from weakness of sight of both eyes about two years duration. The cyst communicated to ventricular system was revealed by pneumo-ventriculography.

The second patient was admitted to our hosp-ital with the complaint of disturbance of gait. Spastic paresis was observed in his both legs. In this case, the cyst was revealed by pneu-moventriculography while in the spinal cord mvelography suspected the existence of ad-hesive arachinitis.

The third patient have suffered from typi-cal hydrocephalus and complained of repeated attack of headache, vomiting and instability of gait since one year ago. In this case, en-largement of Cavum septi pellucidi and par-tial defect of septum pellucidum were sug-gested by iodine-oil ventriculography, and were proved by craniotomy.

In my opinion, it emphasized that more attention should be paid to this disease, be-cause it is thought as more comon cause of various neurological disorders, in spite of report of this desease is rare in Japan.
