Inflammatory pseudotumor which had four years of imaging stability. Axial (A) and coronal (B) T2-weighted images show a T2-hypointense soft tissue mass surrounding the central intrahepatic and extrahepatic duct (arrows) and a high-grade stricture of the mid common bile duct and mild upstream biliary duct dilation (arrowhead). Axial post-contrast T1-weighted images in the portal venous phase show confluent homogenous enhancement within the mass (arrow). There were morphologic features of advanced fibrosis or cirrhosis with marked splenomegaly (asterisk) secondary to portal hypertension
