title: [A case of angiomatous meningioma near the geniculate ganglion].
abstract: A 57-year-old male was admitted with pulsatile tinnitus 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 conductive 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 partly with meningotheliomatous meningioma. Meningioma in this region is very rare. We discussed its clinical and radiological characteristics in comparison with chemodectoma and facial neurinoma at the geniculate ganglion.
