"Different from the liver parenchyma that has dual supply, portal vein, and hepatic artery, the intrahepatic biliary ducts are exclusively supplied by the peribiliary plexus, which branches from the hepatic artery 1-2. The extra-hepatic ducts have multiple extra-hepatic blood supplies making them less vulnerable to developing necrosis 2."

"Differential diagnosis "
"embolic disease (e.g. atrial fibrillation)"
"Biliary infarct will manifest as wall irregularities and beading dilatation appearances of the intrahepatic bile ducts associated with marked surrounded hypoattenuation. Multiple cavitations/bile lakes are also characteristic in advanced necrosis; however, the presence of gas is frequent and does not necessarily represent infection 1,3."
