Abstract

To explore the computed tomographic (CT) manifestations and their values in the diagnosis of intrahepatic cholangiocarcinoma (IHC) and improve the understanding of IHC. A total of 58 IHC patients confirmed pathologically from January 2006 to December 2012 were reviewed. On plain CT scans, all lesions were of low density with lower density region (n = 37), retraction of liver capsule (n = 11), dilation of intrahepatic biliary duct (n = 22), bile duct calculus (n = 13) and atrophy of liver lobe (n = 14).On enhanced scans, most tumor showed obvious circular enhancement on arterial phase, stripe and network enhancement of internal region on portal phase and obvious enhancement on delayed phase. CT manifestations of intrahepatic cholangiocarcinoma are specific for its diagnosis.
