Emergency Body CT > Inflammation > Cholecystitis


Acute cholecystitis is inflammation of the gallbladder, usually from impaction of a gallstone within the cystic or common bile duct. Ultrasound is the preferred imaging method to confirm cholecystitis in the appropriate clinical setting. However, many of the pathologic findings can be demonstrated on CT. CT findings of cholecystitis include:

1. Cholelithiasis
2. Gallbladder wall thickening
3. Pericholecystic fluid.

Complicated cases may reveal perforation or hepatic abscess formation.
