(A) Axial T1 weighted post-contrast and axial and coronal T2-weighted images. (B and C) Intraluminal papillary masses appearing hyperintense on T2-weighted images filling the suprapancreatic common bile duct, extending proximally into common hepatic duct, primary confluence and further into right hepatic duct and sectoral ducts of segments V, VI, and VII of right lobe of liver causing their aneurysmal dilatation (red arrows in B and C) with no significant post-contrast enhancement (yellow arrow in A); (D and E) Diffusion-weighted images with ADC maps show areas of restricted diffusion within the lesion (green arrow)
