title: Gallbladder Fossa Abscess Masquerading as Cholecystitis After Cholecystectomy.
abstract: We present a case of a 59-y-old woman who had undergone cholecystectomy and was subsequently found to have an abscess within the gallbladder fossa. A hepatobiliary scan using (99m)Tc-diisopropyliminodiacetic acid demonstrated the characteristic rim sign, a photopenic defect surrounded by a rim of mildly increased activity immediately adjacent to the gallbladder fossa. The rim sign was thought to be the result of reactive inflammation in the hepatic tissue adjacent to a postoperative abscess within the gallbladder fossa.
