XU Qing-yu

Abstract

Objective:To analyse the CT and MRI features of tumors in the cerebellopontine angle.Methods:Twenty-four pathologically proved cases,including 10 cases of acoustic neuroma,7 cases of meningioma,4 cases of trigeminal neuroma,2 cases of epidermoid cyst,1 case of arachnoid cyst.Male (11 cases)and female(13 cases) are between 16～74 years old,The average age is 48 years.Results:Certain CT and MRI charateristics were demonstracted in this group of tumors.Conclusion:CT and MRI is of great value in diagnosis of tumors in the cerebellopontine angle.
