Abstract:
Objective To evaluate the value of magnetic resonance imaging features in differentiating soft tissue lipoma from well-differentiated liposarcoma.Methods MR images of 30 patients with histologically verified fat-containing tumors(22 lipomas and 8 well-differentiated liposarcomas)were retrospectively reviewed.Well-differentiated liposarcomas and benign lipomas were compared in terms of the size of the lesion,percentage of adipose component,number of thick septa,nodular and(or)patchy nonadipose component,contrast enhancement patterns and the margin characters of the lesion.Results The mean size of lipomas[(64?35)mm]was significantly smaller(t=4.263,P
