There is a fat attenuated strip surrounding the superior margin of the body and splenium of the corpus callosum.
Case Discussion
Curvilinear pericallosal lipomas are usually thin, elongated and curvilinear along the corpus callosal margin, as well illustrated by this case. A mildly hypoplastic corpus callosum can be associated with these lesions, but was not present in this case.
