頻回の脳内出血発作をみた悪性絨毛上皮腫脳転移例に対する手術経験

SURGICAL TREATMENT FOR METASTATIC LESION OF MALIGNANT CHORIOEPITHELIOMA TO THE BRA N, CHARACTERIZED BY FREQUENT EPISODES OF CEREBRAL HEMORRHAGE

I．はじめに

　最近本邦においても脳卒中に対する外科的療法^1）の必要性が論じられつつあるが，われわれは前後3回にわたり脳卒中様発作を起こした悪性絨毛上皮腫に対し2回におよび開頭術を試み，それぞれ血腫の剔出に成功し，そのつど有意の生活を行なえるまで回復したが，3回目の出血発作でこれを失つた例を経験したので報告する。

1) This is a case of 30 year-old woman with three episodes of cerebral hemorrhage. On two occasions, craniotomy was success-fully removed.

This patient was able to lead a normal life after each operation. The third and the last episode occurred one month following the se-cond. She finally expired. The autopsy reveal-ed a metastatic lesion from malignant cho-rioepithelioma, occupying the almost entire left hemisphere.

2) Incidence of cerebral hemorrhage cau-sed by metastatic lesions from malignant tumors and its operative results have been studied. Discussions have been made on surgical managements of cerebral hemorrha-ge which are currently in problem in this country.
