Cerebellopontine angle meningioma associated with cranial accessory nerve neurinoma--case report.
A 46-year-old female presented with a rare association of cerebellopontine (CP) angle meningioma with accessory nerve neurinoma manifesting as headache, occasional diplopia, speech disturbance, swallowing difficulty, and unsteady gait. Magnetic resonance imaging demonstrated a large tumor in the left CP angle. The tumor was totally removed through a lateral suboccipital approach. During the operation another smaller tumor was found originating from the cranial accessory nerve and was also totally removed. Histological examination found that the larger tumor was a meningotheliomatous meningioma and the smaller an Antoni type A neurinoma. The symptoms were apparently due to the larger tumor. Careful examination of neuroimages is necessary even after the main lesions responsible for the symptoms are identified.
