Reactivation of Crohn’s disease at an ileostomy. a, b CT showing diffuse, mildly irregular mural thickening with marked contrast enhancement along the stomal tract and the distal small bowel, consistent with active disease (also note fat stranding and fluid in the right parietocolic gutter). c, d In the same patient, MR-enterography confirms thickened walls on T2-weighted (c) with hyperenhancement on post-gadolinium fat-suppressed (d) images. Additionally, note enhancing inflamed peristomal skin (thin arrows in a, b and d)
