     Contrast-enhanced CT scans often show hypervascularity of the involved mesentery, manifesting as vascular dilatation, tortuosity, prominence, and wide spacing of the vasa recta (Fig. 11). These distinctive vascular changes have been called vascular jejunization of the ileum or the comb sign [33].
