Mesenteric metastases of purely myxoid liposarcoma: An unusual behavior of primary tumor depicted on fludeoxyglucose positron emission tomography/computerized tomography

Abstract

A 48-year-old male patient with purely myxoid liposarcoma was referred to fludeoxyglucose positron emission tomography/computerized tomography (FDG PET/CT) for restaging. FDG PET/CT images showed a hypodense well-defined intermuscular mass with mild FDG uptake in the right gluteal region. In addition, multiple mild hypermetabolic masses that had similar characteristics with the aforementioned lesion were also revealed in the mesenteric region of abdomen and pelvis.
