Imaging of liposarcoma a A 62-year-old woman with biopsy-proved well-differentiated liposarcoma. Note the large left retroperitoneal mass, which is of predominantly fatty attenuation (arrow). b A 56-year-old man with dedifferentiated liposarcoma. Coronal contrast-enhanced CT shows a large fatty right retroperitoneal mass with areas of soft tissue density (arrow) and coarse calcification (arrowhead). c Pleomorphic liposarcoma in a 60-year-old man. Note the enhancing retroperitoneal soft tissue mass with central necrosis (arrow)
