Whirlpool sign – seen when bowel rotates around its mesentery with the vessels and collapsed bowel creating the whirls. It is found in a number of settings including malrotation complicated by midgut volvulus and caecal volvulus (as above). In midgut volvulus the swirl is counter-clockwise on CT (as if viewed from below) and clockwise on US and is analogous to the corkscrew sign seen on barium studies.
