Objective To investigate the characteristics and regularity of MRI images of common benign lesions in the cerebellopontine angle so as to achieve the purpose of diagnosis and differential diagnosis. Methods The MRI features of 21 cases of cerebellopontine angle tumors in our hospital since 2008 were retrospectively reviewed. Both operation and radiotherapy, results in 12 males and 9 females, the site of the left cerebellopontine angle in 11 cases, the right side of 10 cases. Acoustic neuroma in 7 cases, 5 cases of trigeminal neuroma, meningioma in 4 cases, epidermoid cyst (lipoma) in 3 cases, 2 cases of arachnoid cysts. Conclusion MRI has an irreplaceable role in the diagnosis of cerebellopontine angle tumor.
