Fat-Containing Soft Tissue Lesions of the Limbs and Body Wall-A Pictorial Essay.

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.
