Computed tomography in complicated cholecystitis

The computed tomographic (CT) findings in 23 patients with complicated cholecystitis verified at surgery in 20 cases or autopsy in three cases were analyzed. Gallbladder size, wall thickness, and bile density as determined by CT are nonspecific. Gallstones as the leading diagnostic sign are difficult to identify by CT. Pericholecystitis, inflammatory lesions, and, particularly, abscess formation indicating complications of cholecystitis are readily demonstrated by CT.
