title: Interhemispheric epithelial cyst. Case report.
abstract: We report a rare case of a 54-year-old woman with an interhemispheric epithelial cyst. This will be the first report of an interhemispheric epithelial cyst without callosal agenesis. A partial excision of the cyst wall has led to her recovery with no evidence of recurrence. Ultrastructural studies suggest that the cyst was derived from the primitive neuroepithelium. We discuss the pathogenesis of the interhemispheric epithelial cyst.
