Intracerebral schwannoma of the angular gyrus: case report.

Abstract

We report an intracerebral schwannoma originating in the angular gyrus of a 20-year-old female that was incidentally diagnosed after she presented with a post-traumatic seizure. After comprehensive investigations, including functional magnetic resonance imaging, she underwent a computed tomography-guided stereotactic resection of the lesion. Pathological examination confirmed features of a schwannoma. After six years of follow-up, she remains well, without any evidence of recurrence. Intracerebral schwannomas are extremely uncommon: fewer than 90 cases have been reported. We present a comprehensive summary of the literature and a discussion of novel theories on the pathogenesis of intracerebral schwannomas.
