Acute cholecystitis refers to the acute inflammation of the gallbladder. It is the primary complication of cholelithiasis and the most common cause of acute pain in the right upper quadrant.

The main complications of acute cholecystitis include the following ¹:

• emphysematous cholecystitis
• hemorrhagic cholecystitis 
• pericholecystic abscess (this case): as a result of a perforation of the gallbladder wall; hepatic abscesses can also occur
