Abstract:
Objective To analyse CT and DSA appearances of intrahepatic cholangiocarcinoma,and to improve understanding of intrahepatic cholangiocarcinoma.Methods Plain and enhanced CT scanning were performed in 17 patients with intrahepatic cholangiocarcinoma pathollogically proved,6 patients(6/17) performed dynamic CT scanning,5 performed DSA examinations.Results Pre-contrast CT scanning was a single low density lesions in all patients,post-contrast CT scanning showed slightly inhomogeneous enhancement in 17 patients,3 patients(3/17) showed low density unenhancement area with margin enhancement,2 patients delayed enhancement;Intrahepatic billary delatation was found in 15 patients and was within the lesion in 10 patients(10/15);On DSA,5 patients showed enlaragement increasment and rigidity of supplying arteries and tumour stain.Conclusion CT scanning and DSA were important,investigative methods for intrahepatic cholangiocarcinoma,the billary dilatations with slightly inhomogeneous enhancement lesions is important sign in diagnosising intrahepatic cholangiocarcinoma.
