Intractable seizures.
Patient Data
Age: 18 months
Gender: Male
From the case:
Pericallosal lipoma
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_pin":false},"extraPropsURL":"/studies/49608/annotated_viewer_json?lang=us"}
Abnormal configuration of the interhemispheric area, with an ill defined fat density lesion and abnormally shaped third ventricle.
From the case:
Pericallosal lipoma
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_pin":false},"extraPropsURL":"/studies/49609/annotated_viewer_json?lang=us"}
The MRI shows a dysgenetic corpus callosum (only genu is formed) and the fat intensity lesion at the interhemispheric fissure. No posterior fossa abnormality. Normal lying cerebellar tonsils.
Case Discussion
A fat density / intensity lesion at the interhemispheric fissure is in keeping with a pericallosal lipoma, which is the most common location. There is an association with abnormalities of the corpus callosum as in this case.
