A 61-year-old male with a history of gastric carcinoma referred for suspicious pulmonary and liver findings on CT. (A) Transaxial FDG-PET demonstrates a focus of increased tracer uptake in the mid pelvis (arrow) localized by (B) PET/CT image to the rectosigmoid wall, which appears to be thickened on (C) CT. Following colonoscopy, a large polyp was resected, and the histological examination showed tubulovillous adenoma with moderate dysplasia. CT, computed tomography; FDG-PET, fluorodeoxyglucose-positron emission tomography.
