Three colonic cancers, two sites of complete occlusion, one patient: A case report

Figure 1 Axial contrast-enhanced computed tomography image. A short segment circumferential soft tissue mass within the sigmoid colon and luminal narrowing (arrow) consistent with a tumor. There is a small lymph node adjacent to the lesion.

Figure 2 Coronal contrast-enhanced computed tomography image. A: The proximal right colonic tumor (long arrow) at the level of the ileocecal valve, evidenced by a focal mild circumferential wall thickening. Sigmoid cancer is partially seen (short arrow); B: The middle right colonic tumor (long arrow), evidenced by a focal circumferential wall thickening without obstruction. Sigmoid cancer is partially seen (short arrow).
