Computed tomography enterography (a) reveals extensive small bowel alteration affecting the last 80 cm of the ileum, characterized by the presence of multiple thick-walled and reduced-caliber tracts alternating with normal or increased caliber tracts, which are also represented in the reconstructions obtained through vessel analysis. In this reconstruction, it is possible to accurately assess the overall extent of the disease and each lesion. Last ileal loop: length of 45 mm, lesion 1: 32 mm, lesion 2: 54 mm, lesion 3: 130 mm, lesion 4: 32 mm, lesion 5: 40 mm. Lesions 2 and 3 exhibit increased density of the perivisceral adipose tissue. Between lesions 3 and 4 and between lesions 4 and 5, the loops are dilated (maximum caliber: 35 mm). Multiplanar coronal reconstruction (b) does not allow the small bowel to be visualized in its longitudinal extension because of the long section of intestine affected by the pathology.
