'''Mass-forming intrahepatic''': tumors will be homogeneous mass of intermediate echogenicity with a peripheral hypoechoic halo of compressed liver. They tend to be well delineated but irregular in outline, and are often associated with capsular retraction, which if present is helpful in distinguishing cholangiocarcinomas from other hepatic tumors.

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
