Abstract
A 33-years-old female was admitted to our hospital because of upper abdominal pain. Abdominal ultrasonography of the abdomen revealed polypi of the gallbladder. And endoscopic retrograde pancreatocholangiography revealed anomalous arrangement of the pancreatobiliary duct without dilatation of the common bile duct.
At operation, the gallbladder was shown to have diffuse multiple polypoid lesions on the mucosal surface and histologically many foamy cells in the lamina propria. From these findings, a diagnosis of diffuse papillomatous cholesterosis with non-dilatation of the bile duct associated with anomalous arrangement of the pancreatobiliary duct was made.
The case is of particular interest in investigating the relation between mucosal change of the gallbladder and anomalous arrangement of the pancreatobiliary duct.
