Classic findings of active inflammatory Crohn disease of the terminal ileum with mural thickening, hyperenhancement, the "comb sign" of mesenteric congestion and mild proximal small bowel dilatation. Endoscopic studies such as enteroscopy or capsule endoscopy, or radiology studies with luminal distension such as CT enterogram, MRI enterogram or barium follow-through provide a better assessment of the proximal small bowel.

Biopsies confirmed small bowel Crohn disease in this case.
