Presentation
15 year old male with epilepsy first started at the age of 5.
Patient Data
MR demonstrates two extra-axial masses within the sulcus in the right frontal lobe. The adjacent sulcus is expanded. The mass was hyperintense on T1 and T2 weighted images, and shows signal loss on T1 fat saturated images. There is moderate blooming on T2GRE images due to possible microcalfications. No diffusion restriction was noted. The findings most suggestive with lipoma. The lipomas surrounding with abnormal thickened and dysplastic cortex. A sizable vessel is seen in the more posterior lesion.
Case Discussion
In most of cases intracranial lipomas occur in the pericallosal, quadrigeminal and superior cerebellar cisterns. Lipomas on the cerebral surface are very rare and usually associated with cortical dysplasia and brain malformations.
