Brainstem auditory evoked potentials (BAEP) were obtained from 13 patients with pontocerebellar angle (PCA) tumors whose pathological diagnosis was as follows: 7 acoustic neurinoma, 3 meningioma, 1 neurinoma, 1 brainstem epidermoid tumor, 1 arteriovenous malformation. Notable abnormalities were observed in the BAEPs generated by stimulating the ear ipsilateral to the lesion. Keywords : Pontocerebellar angle tumors. BAEP
