This is a case of acute calculous cholecystitis. Cholecystitis can be classified as either acute or chronic, and acute cholecystitis can be either calculous or acalculous. Calculous cholecystitis occurs in 95% of cases of cholecystitis, and acalculous cholecystitis occurs in 5% of cases of cholecystitis.

This is treated surgically with cholecystectomy.
