Abstract:
Objective To observe the MR findings of myxoid-round cell liposarcoma of the lower extremities and to evaluate therelationship between MR findings and pathologic features. Methods MR findings of 6 myxoid-round cell liposarcomas of the lowerextremities confirmed pathologically were retrospectively reviewed,including tumor's location,size,morphology,internal architecture and signal intensity characteristics on T_1WI,T_2WI and SPIR T_2WI and the pattern of enhancement.Results All tumors were located in thedeep space among skeletal muscles of the lower extremities,with unregular shape,sharp borber and thick septal structures.Tumors werehomogeneous or heterogeneous isointense on T_1WI and hyperintense on T_2WI relative to the signal intensity of skeletal muscles and heterogeneous enhancement after the injection of GdDTPA.Conclusion MRI may lead to a correct diagnosis of myxoidround cell liposarcoma of the lower extremities.
