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
