A: At arterial phase, the nodule shows early enhancement (arrows); B: The nodule demonstrates contrast agent wash-out in late phase: it was a typical appearance of HCC and proved malignant at histology (arrows); C: Another hypoechoic nodule at IOUS was hypoenhanced in late phase: it was considered intrahepatic metastasis and confirmed malignant at histology (arrows).
