Well-delineated 20.4 x 14.7 x 11 cm lobulated mass in the thigh abutting, but not infiltrating the thigh musculature.
The mass contains multiple thin septae and fatty elements. Mild enhancement of the solid components.
No local lymphadenopathy.
Multiple high T2 foci within the femur, the largest 6cm at the proximal metaphysis.
Comment: appearances highly suggestive of a liposarcoma
The signal changes in the femur suggest osseous involvement.
