MRI findings in periportal infiltrating variety of hepatic lymphoma in a 60-year-old man. Axial (a and b) and coronal (d) T2-weighted and diffusion weighted (c) MR images demonstrating a mildly hyperintense ill-defined juxta-hilar diffusion restricting mass (arrowheads) completely encasing the common bile duct (solid arrow in d) and vessels at porta with resultant upstream biliary dilatation (interrupted arrows). A vertebral lesion is also seen (solid arrow in b and c) along with perihepatic and splenic hilar lymph nodes (asterisks in c)
