Ischemic cholangiopathy in the setting of chronic hepatic artery thrombosis in a 35-year-old man who underwent liver transplant several years prior for metastatic neuroendocrine tumor. MRCP and coronal T2-weighted image shows severe central-predominant intrahepatic stricturing (thin arrows) and a long segment high-grade stricture of the proximal extrahepatic duct (arrowhead). Note the presence of marked caudate hypertrophy (asterisk, B). Axial post-contrast subtraction images in the arterial phase C show abrupt occlusion of the proximal common hepatic artery (thick arrow). The branch hepatic arteries were reconstituted in the porta hepatitis by multiple small collaterals (thin arrow, C)
