A, B For a 64-year-old male patient diagnosed with superior mesenteric vein occlusion. C–E For a 72-year-old male patient diagnosed with superior mesenteric artery occlusion. A Coronal oblique CT in venous phase showing complete occlusion of the superior mesenteric and portal veins (white arrows) as well as fat stranding around the mesenteric vein (curved white arrow). B Axial CT in venous phase showing mural thickening (white arrow heads) with preserved mural enhancement associated with mild surrounding fat stranding (yellow star). C Coronal CT in arterial phase showing filling defect at the superior mesenteric artery and one of its branches (red arrows) with dilated small bowel loops (yellow arrow heads). D Axial CT in arterial phase showing mural hypo-enhancement of ileal bowel loops (white arrows) compared to normal enhancement of the jejunal loops (green arrows). E Image of resected ischemic bowel loop that approve the CT diagnosis of bowel ischemia
