Biliary papillomatosis

A 74-year-old asymptomatic man was referred to the outpatient clinic by his general practitioner because of abnormal liver enzymes. He had no important medical history. Blood analysis showed mild cholestasis. Abdominal computed tomography showed bile duct dilatation with contrast capturing mural nodules in the common bile duct with protrusion into the dilated lumen (Figure 1a). Magnetic resonance cholangiopancreaticography revealed bile duct dilatation with multiple irregular filling defects (Figure 1b). This article is protected by copyright.
