Ischemic colitis and large bowel infarction: A case report

Figure 2 Contrast-enhanced abdominal computed tomography scans suggesting segmental colitis involving the splenic flexure and the descending colon. A: Coronal sections with zones of mural thickening of the colon just below the splenic flexure and a long and narrow axial stenosis of the descending colon; B: Sagittal sections showing (arrow) the "double halo" sign, a tomographic equivalent of the classic “thumbprinting” that is observed in barium enemas.
