小児聴神経腫瘍の1例—早期診断の重要性について

Acoustic Neurinoma in a Child

I．はじめに

　Von Recklinghausen氏病に伴わない小児の聴神経腫瘍は比較的稀と思われる．

　今回われわれは，早期診断のもとに，外科的治療を行い，顔面神経の機能を温存せしめた小児の聴神経腫瘍の1例を経験したので，文献的考察を加え報告する．

Abstract

A case is reported of acoustic neurinoma unrelated to Von Recklinghausens' disease in a child.

A 14-year-old boy had suddenly become aware of im-paired hearing associated with tinnitus, in August, 1988. He was admitted to our department in October, 1988. On admission, he had no neurological deficits except for right tinnitus. Acoustic tumor was found on air CT and MRI. Total removal of the tumor was achieved through a suboccipital craniotomy. The tumor had ori-ginated in the superior vestibular nerve.
