Two cases of recurrent CD after ileo-colic resection. a–b Proximally to the ileo-colic anastomosis (arrows), the neoterminal ileum (arrowheads) does not distend retrogradely during WE-MDCT and shows thickened walls with enhancing mucosa and perivisceral vascular engorgement (“comb sign”, +). c–d Proximally to the well-distended colon, the ileo-colic anastomosis (arrows) appears moderately patent (arrows). Recurrent CD is depicted as segmental, homogeneously enhancing mural thickening (arrowheads) with mucosal irregularities
