Fig 3. Sixty-three years old man with colorectal cancer.

A, MIP image. Interruption of confluence of the right and left hepatic ducts with biliary tree dilation. In B (axial T2-W HASTE FS) it is evident the presence of peri-intraductal ductal hyperintense tissue at confluence of the right and left hepatic ducts (red arrow) and in peri- left hepatic ducts (yellow arrow), that appear hypointense (red and yellow arrow) in C (axial T1-W in phase) and D (axial T1-W out phase), with progressive contrast enhancement in E (arterial phase) and D (portal phase). On CT study in F (arterial phase there is no evidence of lesion, while in portal phase (G) the tumor (yellow arrow) appears as a hypodense hepatic lesion.
