From: Many faces of acute bowel ischemia: overview of radiologic staging
A 64 y/o male with remote history of abdominal liposarcoma, status post whole abdominal external beam radiation therapy. Diffuse marked small bowel wall thickening (thick arrows) is evident involving bowel loops within the radiation field associated with transmural enhancement suggestive of early ischemia. However, there is small volume pneumoperitoneum (arrowheads), due to CT-occult micro-perforation, suggestive of focal bowel necrosis
