There is a thin curvilinear fat density lesion (HU – 90) seen around the corpus callosum (posterior mid-body, isthmus and splenium). Also, this fat lesion enters into the velum interpositum and right lateral ventricle.
No corpus callosum dysgenesis.
No extracranial subcutaneous lipoma.
Features favour pericallosal lipoma.
