Objective: To investigate the MRI features of tumor in the cerebellopontine angle (CPA) region. Methods: The MRI findings of 100 cases of CPA tumors confirmed by surgery and pathology were retrospectively analyzed. The MRI features were analyzed. Results: There were 51 cases of acoustic neuroma, 18 cases of meningioma, 3 cases of trigeminal neuroma, 15 cases of cholesteatoma (epidermoid cyst), 4 cases of arachnoid cyst, 4 cases of hemangioblastoma, 2 cases of meningioma, 3 cases of cerebellar astrocytoma, aged 2 to 89 years, with an average age of 48.8 years. Various cerebellar region tumors have their own special signs. Conclusion: MRI is of great value in the diagnosis and differential diagnosis of tumors in.
