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.

There are no echocardiography/ultrasound findings associated with [disease name].

Echocardiography/ultrasound may be helpful in the diagnosis of [disease name]. Findings on an echocardiography/ultrasound suggestive of/diagnostic of [disease name] include [finding 1], [finding 2], and [finding 3].


'''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.
OR


'''Periductal infiltrating intrahepatic''': tumors typically are associated with altered caliber bile duct (narrowed or dilated) without a well-defined mass.
There are no echocardiography/ultrasound  findings associated with [disease name]. However, an echocardiography/ultrasound  may be helpful in the diagnosis of complications of [disease name], which include [complication 1], [complication 2], and [complication 3].


'''Intraductal''': tumors are characterized by alterations in duct caliber, usually duct ectasia with or without a visible mass. If a polypoid mass is seen, it is usually hyperechoic compared to surrounding liver.
==Echocardiography/Ultrasound==


'''Contrast-enhanced ultrasound''': may aid with diagnosis of cholangiocarcinoma:
*There are no echocardiography/ultrasound findings associated with [disease name].
*Arterial phase:
OR
:*Peripheral irregular rim-like enhancement
*Echocardiography/ultrasound may be helpful in the diagnosis of [disease name]. Findings on an echocardiography/ultrasound suggestive of/diagnostic of [disease name] include:
:*Heterogeneous central hypoenhancement
**[Finding 1]
*Portal venous phase / delayed phase:
**[Finding 2]
:*Decreased echogenicity relative to background liver ("wash out")
**[Finding 3]
OR
*There are no echocardiography/ultrasound findings associated with [disease name]. However, an echocardiography/ultrasound  may be helpful in the diagnosis of complications of [disease name], which include:
**[Complication 1]
**[Complication 2]
**[Complication 3]
