53-year-old male patient with liver cirrhosis and right hepatic lobe segment VII/VIII HCC underwent radiofrequency ablation on January 2019. Follow-up post-intervention triphasic CT was done on February 2019 and revealed evident intra-lesional pathological enhancement, denoting residual/recurrence activity of this lesion. CTP functional maps showed marked increase in blood flow to the lesion measuring about 233 mL/100 g/min compared to 67 mL/100 g/min in the rest of hepatic parenchyma. In addition, the mean transit time is reduced to become 6 s
