Because of its indolent course, high recurrence rate, and risk of malignant transformation, mucinous biliary papillomatosis is an important consideration in the differential diagnosis of bile duct obstruction. We report a case of mucinous biliary papillomatosis and review the sonographic and other imaging findings previously reported in the literature. On sonography, these tumors appear as nonshadowing intrabiliary masses that are clearly defined and associated with proximal biliary dilatation. They may be multiple and associated with mucoid sludge. The imaging findings reflect the macroscopic appearance of a doughy papilliferous tumor of a bile duct. Associated findings include cholelithiasis, choledocholithiasis, and gallbladder dysplasia. © 1998 John Wiley & Sons, Inc. J Clin Ultrasound 26:151–154, 1998.
