Imaging findings of biliary hamartomas

Figure 2 A 72-year-old man with VMCs. A: On B-mode US, multiple small hyperechoic lesions were shown, while hypo-echoic lesions were not evident on the conventional scanning plan. However, with the use of zoom function, the hypoechoic lesion with comet-tail echo was clearly shown (arrows); B: On MR cholangiopancreatography, multiple small hyper-intensity lesions were revealed except for the demonstration of normal intrahepatic and extrahepatic bile ducts. In addition, several small cysts in the right kidney were also shown.
