Porcelain Gallbladder

porcelain gallbladder

This coronal reformat of a CT scan performed on a 74 year-old woman shows porcelain gallbladder.

The high density is due to calcium carbonate encrustation of the gallbladder wall. It is associated with gallstones in 90% (this patient had a gallstone). It is seen in around 1% of cholecystectomy specimens. Subsequent gallbladder carcinoma develops in 10-20% of patients.
