The representative patients with low risk and high risk of early postoperative recurrence. A 57-year-old woman with a 7.2 cm moderately differentiated HCC in hepatic segment V/VI, serum AFP level of 4.11 ng/mL, ALT level of 33 IU/l and AST level of 23 IU/l was divided into low risk group of Early postoperative recurrence after curative resection. The mass of this patient was a single nodule which showed non-rim hyperenhancement on arterial phase (a), no washout on portal venous phase (b) and hypointensity on hepatobiliary phase (c). This patient did not undergo recurrence during one-year follow up. A 44-year old man, who was identified with high risk of early postoperative recurrence, showed a 13.3 cm poorly differentiated HCC in hepatic segment VI/VII, serum AFP level of 706.5 ng/mL, ALT level of 40 IU/l and AST level of 64 IU/l. A mass of this patient showed non-rim hyperenhancement on arterial phase (d), non-rim washout, corona enhancement(arrow) and tumor in vein(arrowhead) on portal venous phase (e). Besides, it was a single nodule with extra-nodular growth, which showed hypointensity and peritumoral hypointensity (arrow) on hepatobiliary phase (f). The recurrence-free survival of this patient was 7.4 month
