Acoustic schwannomas are benign tumors that originate from Schwann cells surrounding the vestibular (eighth) nerve, usually within the internal auditory canal [1]. As the tumor enlarges, it fills the canal and extends into the cerebellopontine angle. Acoustic schwannomas are relatively uncommon with an incidence of approximately 1 new case per 100,000 [1]. The mean age at diagnosis is approximately 45 to 47 years, and there is a slight female preponderance [2].
