Tubulonodular pericallosal lipoma and callosal dysgenesis

Case contributed by Dr Saeed Soltany Hosn

Presentation

The patient is a 3 month old female infant presented with febrile convulsion in the setting of upper respiratory tract infection. She was born from noncousin parents, having no remarkable medical history. CT scan underwent for the further evaluation.

Patient Data

Age: 3month
Gender: Female

CT scan shows a hypoatenuating sharply demarkated mass lesion associated with calcification which developed in the interhemispheric fissure  in the anatomical location of the rostrum and genu  of the corpus callosum. There is also partial agenesis of the corpus callosum induced by this mass. There is no evidence of brain swelling.

Case Discussion

Incidental finding of an intracranial lipoma with partial agenesis of the corpus callosum in an infant with Febrile seizure. 

The infant underwent a sepsis workup and discharged from the hospital in a good situation. At the first glance the mass may be misinterpreted as air but a careful radiologist finds it nothing but fat. While intracranial lipoma and pneumocephalus can look identical, but by changing the  window or finding the presence of the calcification there, discrimination is possible.
