At 8 months, the patient's positron emission tomography and computed tomography (PET-CT) scan showed supra and infra-diaphragmatic lymph nodes with peritoneal, omental, perihepatic, mesenteric, splenic deposits and a hypodense lesion with focal uptake in the right lobe of thyroid (Stage IVBX) (Figure 1).
Post-chemotherapy PET-CT scan images. The images are showing a complete metabolic response of lymph nodes with right thyroid uptake (yellow arrow).

FIG2
Post six cycles of R-CHOP, the PET-CT scan was in complete metabolic remission with an FDG (fludeoxyglucose F18) non-avid mesenteric mass of 2 x 2 cm and a hypodense nodular lesion in the right lobe of the thyroid (Figure 2).
