Fig. 3From: MRI features of combined hepatocellular- cholangiocarcinoma versus mass forming intrahepatic cholangiocarcinomacHCC-CC (long arrow) and HCC (short dashed arrow) in the same liver; show similar T2-WI imaging characteristics (a). However the HCC tumor shows intra-lesional fat on in-opposed phased subtraction image (b), arterial phase hyper enhancement (c) and washout (d) compared to the cHCC-CC tumor, which shows no internal fat (b) heterogeneous arterial enhancement (c) and no washout (d). The presence of two different enhancement patterns in similar sized lesions in the same liver should prompt biopsy to confirm that both are HCC as cHCC-CC can occur in the same liver as HCC given the overlap of risk factorsBack to article page
