case_images: The abdomen CT with intravenous contrast disclosed a significant thickening of the wall of the third, fourth duodenum, and of the proximal part of the jejunum with infiltration of the loco-regional fat (Figure 1).
case_images: Angiography demonstrating active bleeding (arrow) in one of the branchs of the jejunal arteries.

case_images: Angiography demonstrated that the bleeding originated from a jejunal branch and microcatheter embolization was successful initially (Figure 2).
case_images: Microscopic examination (hematoxylin-eosin, x150) of the operative specimen. Ulcerative ileitis, the mucosa is replaced by a granulation tissue.

case_images: Histology of the jejunal resection showed a severe mucosal necrosis with loss of villi (Figure 3).
case_images: High-power microscopic examination (hematoxylin-eosin, x400) revealed vasculitis. Some endothelial cells present cytomegaly, suggestive of CMV infection (arrows). The presence of CMV in the jejunum was demonstrated by immunohistochemistry (inset; immunoperoxidase, x400).
