Intraductal papillary neoplasm of the bile duct in a 67-year-old female. a Axial T2-weighted magnetic resonance imaging displays intraductal heterogeneous cystic and tissular mass (star) with dilated bile duct in contact (arrows). The cystic part of the mass is better seen at magnetic resonance cholangiopancreatography (b), and so are the upstream biliary dilatation (arrows) and the connection to the biliary tree (arrowhead). c and d Axial T1-weighted non-enhanced magnetic resonance imaging on arterial phase shows a highly enhanced tissular part
