Computed tomography evaluation of liposarcoma

The role of computed tomography (CT) in the evaluation of lipogenic tumors, lipoma and liposarcoma, was investigated. Six surgically proven cases of liposarcoma and twenty-five lipoma were studied preoperatively by Ct, US and angiography. A significant difference between liposarcoma and lipomas in the CT value was found. Comparing CT findings with pathologic findings in liposarcomas, it is a tendency that CT value of the differentiated liposarcoma shows fat density, and CT value of the undifferentiated type appears soft tissue density with marked contrast enhancement after intravenous injection of contrast material. The usefulness of CT in liposarcoma has been considered that CT could presume T-factor and G-factor before surgery. (author)
