We experienced a typical rare case of dedifferentiated liposarcoma. MRI showed that the mass was consisted of two different elements. The proximal element showed high intensity with T1WI and low intensity with T2WI. The other, a distal element, showed low intensity with T1WI and iso-intensity with T2WI. From these images, we diagnosed this mass as dedifferentiated liposarcoma.
We resected the mass around the marginal margin, and found that it was dedifferentiated liposarcoma, histologically.
The patient is alive without reccurence.
