LIPOMA OF THE CORPUS-CALLOSUM - 3 CASE-REPORTS AND A REVIEW OF THE LITERATURE

Lipoma of the corpus callosum is a rare congenital intracranial tumor. Although only 153 cases had been reported as of March 1992, the incid ence of this tumor is underestimated (some cases are unpublished and o thers are asymptomatic). Three cases of lipoma of the corpus callosum diagnosed in children are reported herein. These tumors may be either discovered fortuitously in an asymptomatic patient or responsible for manifestations Of which the most common are seizures, headache, and me ntal disorders. Diagnosis rests on imaging techniques. The main invest igation is computed tomography which discloses a mass composed of fat, with or without peripheral calcifications, and also identifies any ot her malformations such as dysgenesis of the corpus callosum.
