Overview

On CT scan, cholangiocarcinoma is characterized by homogeneously low in attenuation and demonstrate heterogeneous minor peripheral enhancement with gradual enhancement centrally. Capsular retraction may be observed.

CT scan

  • Abdominal CT scan may be helpful in the diagnosis of cholangiocarcinoma. Findings on CT scan suggestive of cholangiocarcinoma include:[1][2]
    • Capsular retraction
    • Dilation of bile ducts distal to the mass
    • Narrowing of the portal veins or hepatic veins
    • Lobar or segmental hepatic atrophy associated with vascular invasion
