Synchronous duodenal and colonic advanced adenomas during post-colorectal cancer surveillance

A 78-year-old man with a sigmoidectomy history for pT2N0M0 colon adenocarcinoma presented with elevated carcinoembryonic antigen. 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) was performed for comprehensive evaluation which indicated multiple high FDG uptake lesions suspicious for malignancy (Fig.  1). Subsequent esophagogastroduodenoscopy (EGD) and colonoscopy respectively revealed a 30-mm semipedunculated polypoid lesion in the duodenum and an 8-mm sessile polyp in the ascending colon (Fig. 2) but without the sign of anastomotic recurrence.
