title: Epidermoid tumor arising in the anterior interhemispheric fissure.
abstract: There have only been 18 cases reported in the literature of an epidermoid tumor arising in the interhemispheric fissure. We report a 45-year-old woman with an epidermoid tumor arising in the interhemispheric fissure. She presented with a focal convulsive seizure. Radiological imaging identified a tumor in the interhemispheric fissure, which was subtotally removed due to adherence to both anterior cerebral arteries and the cerebral cortex. Epidermoid tumor was confirmed by histopathology. Epidermoid tumors rarely arise in the interhemispheric fissure, but are often adherent to surrounding structures and thus, as in the presented case, complete resection may be unwise.
