title: False-negative morphine-augmented cholescintigraphy: a case of subacute gallbladder perforation.
abstract: The gallbladder and an infected pericholecystic biloma secondary to subacute perforation were visualized during morphine-augmented cholescintigraphy. Perforation of the gallbladder may relieve cystic duct obstruction and contribute to false-negative visualization in the setting of acute cholecystitis.
