MULTICENTRIC 8TH CRANIAL NERVE SCHWANNOMA

To our knowledge, only 3 histopathologically proved cases of multicent ric eighth cranial nerve schwannoma have been described in the literat ure since 1981. We describe a patient with 2 isolated eighth cranial n erve schwannomas arising separately from the left cochlea and internal auditory canal. These 2 tumors were diagnosed using magnetic resonanc e imaging prior to resection, and the diagnosis was further confirmed by intraoperative findings and histopathologic analysis. The genetic m olecular basis and clinical features of this rare tumor have been over looked. The value of the transotic approach for total tumor removal is emphasized.
