Abstract
|
|
|
Intra- and extrahepatic bile duct can be invaded by hepatocellular carcinoma (HCC). This is infrequent in HCC, but it can directly affect the clinical manifestation and prognosis. We present eight cases of HCCs with emphasis on the incidence and
features of bile duct invassion on computed tomography (CT).
Over a period of 22 months, abdominal CT was performed in 186 with HCC patients. Out of these, five cases of bile duct invasion by HCC were confirmed in our hospital and three in other hospitals. The eight cases were evaluated for the type, size
and
location. CT features of intraductal mass and ductal dilatation were evaluated.
The incidence of bile duct invasion in HCC was 2.6%. Infiltrative type of HCC was seen in seven cases and six of these had mass 5-11 cm in size. The characteristic CT findings of bile duct invasion in HCC are mass in common hepatic duct with
bulging
contour(8/80, multiple intraductal masses in the intrahepatic ducts (5/8), and diffuse dilatation of intrahepatic ducts (7/8).
