MRI and CT of Bilateral Intraosseous Lipomas of the Sphenoid Body - A Case Report

Mahnoor Hafeez

Abstract


We describe the case of a 12-years old male who was referred to the Civil Hospital in August 2016 with symptoms of generalized tonic clonic seizures. His MRI of the brain showed well bilateral lobulated hyperintense lesions occupying the body of the sphenoid bone. The lesion was hyperintense on T1- and T2-weighted sequences with central foci of hypointensity, without enhancement of the lesions after i.v. gadolinium injection. The CT scan revealed bilateral expansile osteolytic hypodense lesions involving the sphenoid body with central foci of calcification and the average Hounsfield Unit value of the lesions ranging from −85 to −90 HU confirming the fatty nature of the tumor. The radiologic features were consistent with intraosseus lipoma of the sphenoid bone, which is extremely rare1. To best of our knowledge, we are reporting the first case of bilateral sphenoid intraosseus lipomas with characteristic MR and CT imaging features.

Key words: bilateral, Intraosseous lipoma, sphenoid body, CT, MR.
