Abstract

Objective To analyze the MRI features of tumors in the cerebellopontine angle.Methods The MRImanifestations of 100 pathologically proved cases were analyzed retrospectively and the MRI features were cocluded.Results Of the 100 cases,51 were acoustic neuroma,18 were meningioma,3 were trigeminal neuroma,15 were epidermoid cyst,4 were arachnoid cyst,4 were hemagioblastoma,2 were ependymocytoma,3 were cerebellar astrocytoma.Male(41 cases)and female(59 cases)are between 16～74 years old,The average age is 48.8 years.Certain MRI charateristics were demonstracted in this group of tumors.Conclusion MRI is of great value in diagnosis of tumors in the cerebellopontine angle.
