Pericallosal lipoma


Intracranial lipomas are congenital lesions, most commonly found in a pericallosal distribution. Pericallosal lipomas are divided into tubulonodular and curvilinear subtypes, and can be associated with corpus callosum dysgenesis. Extension into the choroid plexus and lateral ventricles can occur. Other sites for intracranial lipomas include the quadrigeminal plate cistern, suprasellar cistern and cerebellopontine angle.
