Female patient, 48 years old. Physical examination found liver mass. Physical examination: the abdomen did not touch the clear mass. Laboratory tests: AFP 4.96 ng / ml, carcinoembryonic antigen 0.5 ng / ml, carbohydrate antigen 19 ~ 94.4 U / ml, are located in the normal range.

Ultrasound (Fig. 1): The livers of the left outer lobe mass began to appear in the central region of the 11-s phase of the arterial phase, with an atypical spoke-like shape.
