Overview
On abdominal ultrasound, cholangiocarcinoma is characterized by obstruction and dilation of bile ducts. Mass-forming intrahepatic cholangiocarcinoma is characterized by homogenous mass of intermediate echogenicity with a peripheral hypoechoic halo of compressed liver. Periductal infiltrating intrahepatic cholangiocarcinoma is characterized by capsular retraction. Intraductal cholangiocarcinoma is characterized by alterations in duct caliber, usually duct ectasia with or without a visible mass.
Echocardiography/Ultrasound
- Contrast-enhanced ultrasound may be helpful in the diagnosis of cholangiocarcinoma. Findings on an ultrasound diagnostic of cholangiocarcinoma include:
- Arterial phase:
- Peripheral irregular rim-like enhancement
- Heterogeneous central hypoenhancement
- Portal venous phase/delayed phase:
- Decreased echogenicity relative to background liver ("wash out")
- Findings on an ultrasound diagnostic of mass-forming intrahepatic cholangiocarcinoma include:
- Capsular retraction
- Homogeneous mass of intermediate echogenicity with a peripheral hypoechoic halo of compressed liver
- Findings on an ultrasound diagnostic of periductal infiltrating cholangiocarcinoma include:
- Altered caliber bile duct (narrowed or dilated) without a well-defined mass
- Findings on an ultrasound diagnostic of intraductal cholangiocarcinoma include:
- Alterations in duct caliber, usually duct ectasia with or without a visible mass
