Figure 4

A 51-year-old man suffering from hepatitis B for 20 years with elevated AFP level of more than 400 ng/mL. (a) US pre-CEUS showed heterogeneous texture in the right liver lobe and no well-defined lesion was visible in this section. (b) US post-CEUS showed multiple small lesions with clear border (↑). (c) Biopsy was performed in these small lesions under the guidance of US post-CEUS. These new lesions were confirmed as HCC by pathology.
