Abstract

Trigeminal neurinoma is a rare condition arising from the gasserian or trigeminal nerve root. It comprises 0.2% of all brain tumors, and usually affects middle life, but about 10% of it appears in adolescents. Middle fossa syndrome, symptoms and signs of cerebellopontine angle tumor and mixture of these may be developed through the extension of the tumor. Symptoms and signs of cerebellar and midbrain compression may also be elicited in some stage of the tumor. Erosion of the Anteromedial portion of the petrous apex and defect of the flow of the middle fossa contribute to the diagnosis. Air studies and cerebral antiography have been used, and recently pantopaque basal cisternography has been introduced. The route of operation depends upon the main localization of the tumor, but transtemporal approach with tentorial section is widely used for dumbbell-shaped tumor. A case of cerebellopontine angle tumor which had been postoperatively proved to be a trigeminal neurinoma is reported.
