Abstract

We report an 18 F-FDG PET/CT scan of a 47-year-old man diagnosed with diffuse mast cell sarcoma with lymph node, bone, liver, spleen, and lung involvement. This interesting image should remind colleagues to consider mast cell sarcoma as a rare differential diagnosis in patients with multiple, intensely hypermetabolic lesions in various organs and lymph nodes.
