Figure 1 Colonoscopic polypectomy. A: Colonoscopy showing a villous polyp; B: Submucosal saline injection under the villous polyp; C: Electrocoagulation polypectomy done on the lifted polyp.

Figure 2 Initial and follow-up contrast-enhanced computed tomography. A: Axial portal phase image shows a target-like lesion in the right side colon with bowel and fatty mesentery inside and colon wall thickening with submucosal swelling and highly attenuated infiltration of adjacent pericolic fat; B: Coronal portal phase image shows invagination of the right side colon; C: Axial portal phase shows resolved state of previously seen colon wall swelling and target-like lesion; D: Coronal portal phase image shows resolved state of previously seen invagination.
