原発性多発性脳腫瘍—左聴神経鞘腫と側脳室髄膜腫を併存した症例

MULTIPLE PRIMARY BRAIN TUMORS:AN ACOUSTIC NEURINOMA ASSOCIATED WITH MENINGIOMA IN THE LATERAL VENTRICLE; A CASE REPORT

はじめに

　原発性多発性脳腫瘍の報告はかなり見られるが，種類および発生部位の異なる2つの腫瘍の存在を術前に診断し，それぞれの手術に成功した症例の報告は極めて少ない。最近私共は，左小脳橋角部腫瘍と側脳室内腫瘍の併存を術前に診断し，それぞれの摘出手術に成功した1症例を経験したのでここに報告する。

A case of multiple primary brain tumors-a left acoustic neurinoma associated with a meningioma in the lateral ventricle-in patient of 23 year-old woman is described. The tumors were removed successfully in two successive operations.

The coexistence of acoustic neurinoma with meningioma in the lateral ventricle is extraordinery uncommon.

The preoperative diagnosis of multiple brain tumors has been rarely made and the successfully operated cases have been reported on rare occasions.

The therapeutic problems of these tumors are discussed.
