A CASE OF ADENOMYOMATOSIS AND CHOLESTEROLOSIS OF THE GALLBLADDER ASSOCIATED WITH ANOMALOUS ARRANGEMENT OF THE PANCREATICOBILIARY DUCT

Abstract

A 59-year-old female visited our hospital because of persistent epigastric pain. As US study of the gallbladder showed thickening of the wall and multiple polypoid lesions, she was admitted for further evaluation. ERCP revealed narrowing of the lumen of the gallbladder from the body to fundus, serrated changes of the margin of the fundus, and multiple polypoid lesions in the gallbladder. Moreover, abnormal connection of the common bile duct and main pancreatic duct of non-dilatation type was noted. From these findings, a diagnosis of adenomyomatosis and cholesterolosis of the gallbladder associated with anomalous arrangement of the pancreaticobiliary duct was made. This case is of particular interest in investigating the etiology of adenomyomatosis and cholesterolosis of the gallbladder.
