title: CT features of intraductal intrahepatic cholangiocarcinoma.
abstract: OBJECTIVE
  The objective of this report was to describe the CT features of intraductal intrahepatic cholangiocarcinoma.
  
  
  CONCLUSIONS
  Segmental or lobar dilatation of the intrahepatic bile ducts associated with or without intraductal polypoid mass, amorphous structures, or both with slight hyperattenuation are common CT findings of intraductal intrahepatic cholangiocarcinoma. The size of the intraductal mass determines the visibility on CT.
