Objective To provide clinical identification of cerebellar angle tumor and surgical treatment basis. Methods The clinical data of 11 cases of cerebellopontine angle tumor were retrospectively analyzed. Results Among the 11 tumors, 6 (54.5%) had acoustic neuroma, 3 (27.3%) had meningioma, 1 had epithelioid cyst (9.1%) and 1 had trigeminal neuroma (9.1%). The average age of 44.6 years, the average duration of 4.36 years. Clinical manifestations: one side of hearing loss in 9 cases, 6 cases of ataxia, headache in 1 case. MR I confirmed rate of 90.9% (10/11). Occipital approach in 9 cases, supratentorial approach in 2 cases. Tumor resection rate 90.9%, facial nerve retention rate 90.9%, 9 cases of postoperative improvement in symptoms, maintaining the status quo in 2 cases. Eleven cases were followed up for an average of 2.8 years. 10 cases of self-care life, relapse in 2 cases. Conclusion There are many types of cerebellopontine angle tumors. The clinical identification mainly depends on the imaging examination, and the surgical result is satisfactory.
