Abdominal Wall Desmoid Fibromatosis Mimics Sarcoma With Intense FDG Uptake on FDG PET/CT

: We present the case of an abdominal wall soft tissue mass with intense FDG uptake in a 61-year-old man with unintentional weight loss. The appearance of this mass and high focal FDG uptake mimics high-grade sarcoma on (18)F-FDG PET/CT. However, the final excisional histopathological diagnosis was desmoid fibromatosis.
