Abstract: Objective To comparatively analyze CEUS features of hepatitis B virus (HBV)-related combined hepatocellular-cholangiocarcinoma (CHC) and hepatocellular carcinoma (HCC).Methods Thirty-one patients with HBV-related CHC and 31 patients with HBV-related HCC confirmed by pathology were enrolled and CEUS features were compared.Results On CEUS,HBV-related CHC and HBV-related HCC mainly manifested as hyper-enhanced in arterial phase and hypo-enhanced in portal phase and delayed phase.No significant differences of enhancement level on CEUS were found between HBV-related CHC and HBV-related HCC.When the maximum diameter of tumor ≤3.0 cm,both HBV-related CHC and HBV-related HCC were mainly homogeneous enhancement (P=1.000).When the maximum diameter of tumor more than 3.0 cm,diffuse heterogeneous enhancement and peripheral irregular rim-like enhancement were more commonly observed in HBV-related CHC,while diffuse heterogeneous enhancement was more commonly noted in HBV-related HCC (P=0.001).Conclusion The enhancement pattern of HBV-related CHC ＞3.0 cm has relative specific performance.
