ABSTRACT

Diagnosis: Intraosseous Lipoma

History: A 45-year-old female with no significant past medical history presented to the emergency department with a painful knee following a fall from standing height.

Findings: CR, CT, and MR demonstrate a well-defined lytic lesion in the distal femur with mixed fluid and fat attenuation and scattered calcification.

Ddx: Fibrous Dysplasia, ABC, Hemangioma, Bone Infarct, Chondroid Tumor, Intraosseous Lipoma

Dxhow: radiographically

Exam: Tender to palpation over patella.

No MeSH data available.


MR of the femur reveals that the lesion demonstrates a mixed pattern of high and intermediate signal intensity on T1WI. On T2WI with fat-suppression, the areas of intermediate signal become hyperintense while the areas of high signal suppress. A rim of hypointense signal surrounds the entire lesion as well as being scattered throughout the central portion. These areas remain hypointense on all sequences. Axial T1WI with fat suppression post gadolinium administration shows no enhancement.
