An acoustic neuroma, or vestibular schwannoma, is a schwann cell tumor located in the internal auditory meatus or cerebellopontine angle and is generally benign and slow growing. The tumor is encapsulated and lies underneath the nerve of origination. As the tumor becomes larger, compression of the facial nerve (CN VII), acoustic nerve (CN VIII), or brainstem can occur. Compression of the facial nerve may cause facial paresis or decreased facial sensation, compression of the acoustic nerve may cause hearing loss, and compression of the brainstem may cause ataxic movements and a loss of coordination. Generally, patients present with unilateral tumors that occur sporadically but if linked to neurofibromatosis type 2, patients will present with bilateral tumors.
