title: "Pseudogallbladder" appearance in partial afferent loop obstruction in a patient with cholecystectomy.
abstract: We have described a patient who was admitted to the hospital for evaluation of RUQ abdominal pain 40 years after a Billroth II gastrectomy, as well as a cholecystectomy of which the patient was unaware. Gray-scale abdominal ultrasonography and Tc 99m-IDA hepatobiliary imaging were interpreted as revealing an enlarged gallbladder and cholelithiasis. An obstructed afferent loop of the Billroth II anastomosis had mimicked a gallbladder on ultrasonography and hepatobiliary imaging.
