A Rare Case of Pericallosal-Interhemispheric Lipoma

We are reporting a case of interhemispheric-pericallosal lipoma, associated with bilateral small lateral ventricle choroid plexuses and third ventricle lipoma as well as partial agenesis of splenium of corpus callosum. Presentation in our case does not correspond to existing classification of pericallosal lipoma and as it is very rare, we are presenting it as a case report. Intracranial lipoma itself is a very rare anomaly and account for 0.06% to 0.46%. It represents a group of developmental abnormality of brain parenchyma that occur during embryogenesis, and it is located more frequently (about 50%) in the pericallosal cistern and may extend into one or both lateral ventricles. Pericallosal lipoma can also be associated with varying degree of callosal anomalies.
