A pre-imatinib 18F-Flurodeoxy glucose (FDG) positron emission tomography/computed tomography (PET/CT) maximum intensity projection (MIP) image of the patient showing increased FDG uptake in the left axillary, lower abdominal and pelvic regions. Transaxial computed tomographic images at the level of axilla, L3 vertebra, L5 vertebra and ischial tuberosity (1b, 1d, 1f and 1h) and corresponding fused PET/CT images (1c, 1e, 1g and 1i) showing enlarged and FDG avid left axillary lymph node (1c, arrow), FDG avid lobulated mass in the anterior abdominal wall (1d and 1e), deposit in the right external oblique muscle (1f and Ig), multiple mesenteric (arrow heads) and omental* deposits (1e and 1g). There was soft tissue thickening adjacent to the right ischium involving the right pyriformis and gluteal muscles with increased FDG uptake and soft tissue deposit the subcutaneous plane adjacent to it (1h, 1i -arrow)
