Tensile gallbladder fundus sign

Last revised by Craig Hacking on 8 Feb 2023

The tensile gallbladder fundus sign is positive when the gallbladder fundus is seen to bulge into, and distort, the anterior abdominal wall and is a feature of acute cholecystitis.

It is particularly useful as an early sign of the condition on CT as it has around a 75% sensitivity and 95% specificity for acute cholecystitis in the absence of any other CT features 1.
