Fig. 3. 29-year-old man without underlying disease (patient #8).

A, B. Coronal and axial images obtained from reformatted CT scan performed at time of diagnosis with ischemic bowel disease reveal superior mesenteric vein thrombosis (arrowheads) and layered enhancement of thickened jejunal wall indicating venous ischemia (arrows). Patient had abdominal pain at that time and vital parameters were stable. Patient underwent anticoagulation therapy with Heparin. C. Axial and coronal images of contrast-enhanced CT scan obtained when patient had abdominal pain, which was 54 days after ischemic event, reveal segmental post-ischemic stricture with concentric wall thickening and better enhancement in portal phase than arterial phase (moderate mucosal enhancement during arterial phase and moderate homogeneous enhancement during portal phase). Proximal bowel dilatation is also seen, indicating high-grade obstruction. Patient underwent small bowel resection and anastomosis. D. Gross specimen of resected large bowel reveals approximately twp centimeter long segmental stricture with dilatation of proximal bowel segment, which corresponds with CT image findings (arrows in C and D).
