Abstract

Although the cerbellopontine area is a relatively small portion in the intracranial cavity, various kinds of tumors could be found in this area due to it's anatomical characteristics. There are several cranial nerves, brain stem, aquaduct of Sylvius, cerebellum and important vascultures in this area, so various neurological symptoms and signs could be occurred when the tumor developed in this region. A clinical analysis of 49 patients with cerebellopontine angle tumors during the last 5 years at the department of neurosurgery of C.U.M.C was done retrospectively. There were 19 men and 30 women with mean age of 43.8 years. The most frequent tumor was acoustic neuroma-37 of these patients(75.8%) and followed by meniningioma and ependymoma in frequency. The most frequent clinical symptom were headache and hearing disturbance. On the radiological evaluation, simple plain X-ray film showed normal in 43.3% and CT scan of the brain showed hydrocephalus and asymmetric cistern in 28 % and in 25% of patients respectively. Surgery was done by total extirpation in 19 cases and partial removal in 23 cases and the result were excellent or good in 29 cases.
