A 35-year-old male patient, newly diagnosed case of gastric lymphoma. Initial PET/CT study including whole body PET MIP (a), axial CECT (c), and corresponding fused PET/CT (d) images revealed irregular hypermetabolic gastric soft mass infiltrating the related left hepatic lobe and achieving 22.8 SULpeak. Follow-up PET/CT study revealed complete resolution of the mass in whole body PET MIP (b) as well as axial CECT (e) and corresponding fused PET/CT (f) images denoting CR and CMR according to RECIST 1.1 and PERCIST 1.0, respectively. However, the whole body image (b) showed another newly developed metabolically active lesion at upper lobe of left lung that was a pneumonic consolidative patch in axial images (g) and (h).
