Figure 6.

Surgical specimen [A] identified a topographical coupling of small mesenteric vessels [arrowheads] along the surface of the intestine and extending creeping fat. This anatomical manifestation is the basis for creating the mesenteric creeping fat index. On the corresponding coronal CTE using MIP reconstruction with a thickness of 4.90 mm [B], the resected small bowel [arrow] with prestenotic dilatation [asterisk] has prominent perienteric vasculature [i.e. comb sign] in the creeping fat [yellow dotted line], which is consistent with the surgical specimen. H&E staining section [C] shows enlarged mesenteric vessels in the MAT. CTE, CT enterography; MIP, maximum intensity projection; H&E, haematoxylin and eosin; MAT, mesenteric adipose tissue
