Radiologic features of intrahepatic bile duct adenoma: a look at the surface of the liver

Abstract

We report the radiological features of intrahepatic bile duct adenoma (BDA) in three patients. BDA was shown as a small mass located in the peripheral region of the liver with each imaging modality: a hypervascular mass on angiography and a mass appearing as early nodular enhancement found disproportionately evident compared with their small size and distinct delayed or prolonged enhancement on CT. BDA should be included in the diseases to be differentiated from hypervascular hepatic tumors.
