Abstract:
Objective To evaluate the diagnostic value of CT enhanced scan and delayed CT scan in hepatic cholangiocarcinoma.Methods CT plain scan,enhanced CT scan and delayed CT scan were perfomed in 21 patients with hepatic cholangiocarcinoma pathollogically proved.Results The lesions were low density in all patients on plain CT,of them,14 patients were cystiform,7 cases were solid with intrahepatic biliary duct expansion within the lesions.Incomplete thin rim-like enhancement of the tumor periphery was seen on CT enhanced scan in 10 cases of 14 cystiform,complete enhancement in 3 cases.There was not any change in the 13 patients on portal venous phase,1 case didn't show enhancement,substantial tumors in 7 patients showed slightly enhancement after 1 minute of CT enhanced scan and delayed enhancement was seen after 3~8 minutes.The intrahepatic biliary duct expansion didn't change.The density of the tumor was equal to the liver of the same level or exceeded.Conclusion The complete or incomplete thin rim-like enhancement of the tumor of cystiform periphery on CT enhanced scan,not any change on portal venous phase or substantial tumors with intrahepatic biliary duct expansion in delayed enhancement are the characteristic signs of hepatic cholangiocarcinoma.
