I．はじめに

　髄膜腫は脳腫瘍の13-19％を占めると言われるが側頭骨内に発生した報告は少なく，特に膝神経節部は極めて稀である．著者らは膝神経節近傍に発生し，中頭蓋窩および側頭骨内に進展した症例を経験したので，その臨床所見，放射線学的所見，ならびに，鑑別すべき疾患に関して文献的考察を含め報告する．

Abstract

A 57-year-old male was admitted with pulsatile tinni-tus and hearing disturbance of the right ear and right peripheral facial palsy. Otological examination revealed a pulsatile red mass in his right ear and right conduc-tive hearing disturbance. CT and MRI showed the mass lesion at his right middle fossa near the geniculate ganglion. Right external carotid angiogram disclosed a tumor stain fed by the middle meningeal artery. The tumor was removed via a combination of subtemporal and transmastoidal approaches. Histologically, this tumor was diagnosed as angiomatous meningioma part-ly with meningotheliomatous meningioma. Meningioma in this region is very rare. We discussed its clinical and radiological characteristics in comparison with che-modectoma and facial neurinoma at the geniculate ganglion.
