12y MC Domestic Shorthair with hepatitis, anorexia, and vomiting. There is an irregular, isoattenuating mass (b,d,e: arrowheads)
obstructing the common bile duct and causing intrahepatic biliary distension (a,b,d: open arrows). The mass is located ventral to the
portal vein (b: arrow) and in close proximity to the duodenum (d: asterisk). The fluid‐attenuating, branching bile ducts are visible parallel
to the portal veins (c). The mass was also visible on ultrasound images near the duodenal papilla (f: calipers). Surgical biopsy confirmed
lymphoma.
