CT reveals abnormal diffuse segmental wall thickening at the level of the jejunum (long segment, 18-20 cm) on the left side. There is mesenteric edema and vascular congestion, and some ascites.
Superior mesenteric artery (SMA) and vein (SMV) are patent, and no thrombus was seen.
Findings are most suggestive of non-occlusive mesenteric ischemia and submucosal hemorrhage. Differential diagnosis includes Crohn disease and infectious enteritis.
