Figure 2 LR-M nodule in a 54-year-old man with chronic hepatitis B. A: A nodule with a diameter of 3.6 cm in the right liver lobe was homogeneously hyper-enhanced (arrow) in the arterial phase at contrast-enhanced ultrasound; B: Early washout (53 s) of the contrast agent was observed (arrow); C: Hypo-enhancement (arrow) in the late phase was shown at contrast-enhanced ultrasonography. Elevated alpha-fetoprotein and normal carbohydrate antigen 19-9 level were found by in the serologic data. The nodule was assigned to combined hepatocellular-cholangiocarcinoma lesion according to the diagnostic criteria; D: Both hepatocellular carcinoma (orange arrow) and intrahepatic cholangiocarcinoma (yellow arrow) components were found in histopathologic analysis, resulting in a final diagnosis of combined hepatocellular-cholangiocarcinoma (hematoxylin and eosin staining; magnification, × 100).
