A vestibular schwannoma often called an acoustic neuroma is a benign primary intracranial tumor of the myelin-forming cells of the vestibulocochlear nerve (8th cranial nerve). A type of schwannoma this tumor arises from the Schwann cells responsible for the myelin sheath that helps keep peripheral nerves insulated. Approximately 3000 cases are diagnosed each year in the United States with a prevalence of about 1 in 100000 worldwide.
