Corpus callosum dermoid cyst: A rare entity

Abstract

Dermoid cyst is a congenital lesion that arises due to embryogenic impairment. It accounts for less than 0.3% of all intracranial masses. Herein we report a 30-year-old male who presented with a short history of headache and behavioral disorder. Physical and radiological examination diagnosed it to be a lipoma/epidermoid arising from corpus callosum. The lesion was removed endoscopically and histopathologic examination was performed which confirmed it to be a dermoid cyst. Rarity of the lesion and difficulty in pre-operative diagnosis prompted us to bring forward this case report.

Keywords: Corpus callosum; dermoid cyst; histopathologic.
