Myelolipomatous change in an interhemispheric lipoma associated with corpus callosum agenesis: case report.

Abstract

Interhemisperic lipomas are almost always associated with hypogenesis or agenesis of the corpus callosum. These lesions are stable. We report a case of an interhemispheric lipoma in a 72-year-old man who had undergone myelolipomatous differentiation. Gross total excision of the lesion was performed. Although extremely uncommon, the possibility of myelomatous change should be considered in the differential diagnosis of an intracranial lipoma if it shows some areas of mixed density.
