Giant Fibrolipoma Mimicking Subcutaneous Liposarcoma in Shoulder

Lipomas are the most common lesions in subcutaneous tissues. Fibrolipomas are a rare subtype of lipomas. A patient with the mass growth on the left shoulder within 1 year applied to hospital and a large sized fi xed mass was detected on the localization. The patient underwent to contrast enhanced MRI for diagnosis. The lesion was heterogeneous isointense according to fatty tissue on both T1- and T2-eighted imaging and also had hypointense band shaped areas. Fat saturated series revealed suppression and post contrast series showed enhancement in band like hypointense areas within the lesion. The patient underwent to surgery with preliminary diagnosis of liposarcoma. The lesion was diagnosed as fi brolipoma after pathological examination. In this report, we present a case of fi brolipoma mimicking liposarcoma in MRI examination.
