緒言
多発性脳腫瘍の症状は,その各々の発生部位により,複雑な様相を呈してくるので,診断は非常に困難な場合があり,往々一つの腫瘍によるものとして,その神経症状を無理に解釈するので,他の腫瘍を見逃す場合がある。又その多発性脳腫瘍は,一般に同一胚腫より発生するものであるが,その中でもRecklinghausen氏病を伴つている脳膜腫と聴神経腫との併存例が多く発表されている。最近我々は,桂外科教室に於て,Reckling-hausen氏病を伴わない脳室内脳膜腫と両側聴神経腫との併存例を経験したので,ここに報告する。尚,吾々の渉獵した文献例では,脳室内脳膜腫と両側聴神経腫との併存例は未だ見られない。
The diagnosis of multiple brain tumor is very difficult, because it's symptoms are of-ten complicated. Though one of multiple brain tumor could be diagnosed, then extir-pated, the symptoms due to another tumor are to fail to see very often.
A 20-years-old man who had bilateral acou-stic neurinoma with two meningiomas in late-ral ventricle was experienced in our clinic recently. His two meningiomas in lateral ventricle were extirpated completely. At tnat time, we failed to find any signs due to bilateral acoustic neurinoma which was found in the postmortem examination of this patie-nt. Though the multiple brain tumor which occured from the same germ are chiefly rep-orted, also the meningioma combined with acoustic neurinoma in patients of Reckling-hausen's disease paticularly. We could not find in any literature the report about the meningioma in lateral ventricle combined with bilateral acoustic neurinoma as this case.
