Interruption of gallbladder wall with pericholecystic fluid: a CT finding of perforation

Abstract

In this report, we present an unusual case of gallbladder perforation due to acalculous cholecystitis, masked clinically by acute pancreatitis. Severe abdominal pain referred to the patient's back, nausea, vomiting, and high serum and urinary amylase values were compatible with acute pancreatitis. However, on contrast-enhanced CT, the size and appearance of the pancreas were normal while the gallbladder was abnormally enlarged with a wall defect indicating perforation, soon afterward confirmed by surgery.
