mit Whirlpool-Zeichen in der Computertomographie, coronare Reformatierung.
volvulus in an infant with intestinal malrotation. Ultrasonography showing an epigastric mass with a typical whirlpool pattern (arrow).
The whirlpool sign of the mesentery, also known as the whirl sign, is seen when the bowel rotates around its mesentery leading to whirls of the mesenteric vessels.
The term whirlpool sign is used in other contexts: see whirlpool sign (disambiguation).
It is seen in a number of settings:
- malrotation complicated by midgut volvulus
- it represents the swirling appearance of the mesentery and superior mesenteric vein around the superior mesenteric artery. The direction of swirl is clockwise on ultrasound (viewed from above so-to-speak) and counter-clockwise on CT (as if viewed from below)
- it is the corollary of the corkscrew sign seen on barium studies.
- cecal volvulus and cecal bascule
- cecal volvulus and cecal bascule can have the same appearance, with whirl occurring in the cecal mesentery
- sigmoid volvulus
- closed loop bowel obstruction
- enteritis: similar pattern, but in the opposite direction has been described on ultrasound
- omental torsion
- superior mesenteric artery
- Volvulus des Coecums
- intestinale Malrotation
- Volvulus Mitteldarm
- corkscrew sign
