Callosal dysgenesis and lipoma

Case contributed by Assoc Prof Frank Gaillard
Ultrasound

Transcranial ultrasound of an infant demonstrates a hyperechoic mass in the midline associated with callosal dysgenesis. 

MRI

MRI demonstrates dysgenesis of the corpus callosum, with only the genu seen and without a formed rostrum. In the midline is an interhemispheric lesion which is of high T1 signal, and demonstrates signal drop out on fat-saturated sequences consistent with a pericallosal lipoma

Case Discussion

Typical features of corpus callosum dysgenesis with an associated tubulonodular pericallosal lipoma.
