  Acoustic neuroma, also referred to as vestibular schwannoma (VS), acoustic neurinoma, vestibular neuroma or acoustic neurofibroma, is a benign, slow-growing neoplasm arising from the sheath of the vestibular branch of the vestibulocochlear nerve. It is the most common tumor of the cerebellopontine angle and the internal auditory canal. Symptoms of acoustic neuroma include hearing loss in one ear, noise in the ear, balance problems, and vertigo. The vast majority of cases develop from the Schwann cells investing the vestibular portion of the vestibulocochlear nerve, with less than 5% arising from the cochlear nerve. The superior and inferior vestibular nerves appear to be the nerves of origin with about equal frequency. There are two types of acoustic neuromas: sporadic acoustic neuroma, unilateral and genetic, and bilateral acoustic neuroma. Sporadic, unilateral acoustic neuromas are tumors on one side of the body in 95% of patients. They are caused by sporadic (sudden) nonhere...
