Multiple Symmetric Lipomatosis--MR appearances

Multiple Symmetric Lipomatosis (MSL) is a rare disorder of lipid metabolism which is mainly seen in Mediterranean and eastern European populations, which results in massive fat accumulation mainly around the neck and back. The main differential diagnosis lies between MSL and the fat accumulation of Cushing's disease, and liposarcoma. This case demonstrates that MR imaging is a valuable aid to the diagnosis and treatment of this disease by giving excellent definition of soft tissue and vascular structures, allowing accurate assessment and preoperative planning of the disease.
