A 62-year-old male patient presented with liver cirrhosis and HCC lesion managed by radiofrequency ablation with suspected recurrence: a advanced liver cirrhosis with recently ablated two adjacent hepatic focal lesions [black plus (+) symbols] as evidenced by the signs of intra-lesional coagulative necrosis and right subcapsular juxta-lesional RF needle track, currently presented on follow-up imaging with massive infiltrative territory of heterogeneous hyperenhancement [red plus (+) symbol] on arterial phase MRI; b corresponding color-scale relative enhancement mapped MRI further enhances the intensity and heterogeneity of this infiltrative tumoral hyperenhancement; c and d corresponding time–%relative enhancement curves and quantitative hemodynamic metrics compare the non-viable ablated lesions (black) versus the surrounding massive infiltrative readily washed out hyperenhancement positive for viable large recurrence (red), and compare as well the nearby right lobe advanced cirrhotic background (turquoise) versus the contralateral left lobe relatively less advanced cirrhosis (green)
