A 30-year-old female was admitted to our hospital asymptomatically for the evalua-tion of liver dysfunction. Ultrasonography showed thickening of gall bladder wall and gall bladder polyp. ERCP demonstrated anomalous arrangement of the pancreaticobiliary ductal system without dilatation of the common bile duct and fuzzy irregularity of the gall bladder wall. Cholecystectomy was performed. Histologically hyperplasia of mucosa and hyperplastic polyps were detected in the gall bladder wall. ERCP should be performed to detect the non-biliary dilated anomalous arrangement of the pancreaticobiliary system for patients with thickening of the gall bladder wall by US.
