Patient Data
Age: 20 years
Gender: Male
From the case:
Corpus callosal dysgenesis with tubulonodular lipoma
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/112368/annotated_viewer_json?lang=us"}
Corpus callosum dysgenesis with a small callosal remnant.
Large inter-hemispheric tubulonodular lipoma eliciting high signal on T1 and T2 WI. It extends via the choroidal fissures to involve both choroid plexuses of both lateral ventricles.
On MRS, there's a marked elevate lipid/lactate peaks.
From the case:
Corpus callosal dysgenesis with tubulonodular lipoma
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/112369/annotated_viewer_json?lang=us"}
The tubulonodular lipoma appears of low attenuation with a marginal rim of calcifications.
Case Discussion
Tubulonodular lipoma is usually associated with corpus callosum agenesis/dysgenesis. It frequently demonstrates calcifications. It also may extend into the lateral ventricles and the choroid plexus.
