Ultrasound
Yeh et al have suggested few findings on ultrasound which are suggestive of torsion of gallbladder.[1]
- Sign of a floating gallbladder almost the entire gallbladder is located below the liver and is not in contact with the liver.
- Sign of twisted pedicle, pedicle represents the combined cystic duct, cystic artery, and vein as well as mesentery.
- Signs of an inflamed gallbladder( gallbladder wall is diffusely thickened and hypoechoic).
The thickening of the gallbladder wall may not be uniform. The focal thinning (or normal thickness) at the fundal region may indicate possible perforation or impending perforation inthis area. Localized fluid collections around the gallbladder is suggestive complication.
- Evaluation of blood flow in cystic artery may be done with color doppler. [2]
