Ileitis related to Crohn disease on computed tomography enterography

This axial image from computed tomography enterography (A) in a patient with Crohn disease demonstrates active inflammation of a distal loop of ileum (arrow) with wall thickening and perienteric inflammation (arrowhead). The coronal image from computed tomography enterography (B) also shows active inflammation of a distal loop of ileum (arrow) with wall thickening and perienteric inflammation. Fibrofatty proliferation (arrowheads) is seen around this loop, which stands separate from the remaining bowel.
