The whirlpool sign, also known as the whirl sign, is seen when a structure twists upon itself resembling the rotating masses of water of a whirlpool. Described whirlpool signs include:
- whirlpool sign (mesentery): bowel rotates around its mesentery leading to whirls of the mesenteric vessels
- whirlpool sign (ovarian torsion): whirls of the ovarian pedicle vessels seen in ovarian torsion
- whirlpool sign (testicular torsion): spiral twist of the spermatic cord seen in testicular torsion
