Pictorial review reveals key imaging features of fat-containing soft tissue lesions across the limbs and body wall, highlighting diagnostic differentiation between benign lipomas and liposarcomas.
Lipomatous tumours are frequently encountered on imaging. The spectrum of lipomatous tumours ranges from simple lipomas, which can be monitored clinically, to high-grade liposarcomas, which require timely, multidisciplinary management. The presence of fat within lesions may also be observed in non-lipomatous tumours, as well as in a variety of non-neoplastic conditions. This pictorial review examines the key imaging characteristics of primary lipomatous tumours and other fat-containing soft tissue lesions that can be found in the limbs and body wall.
