Concurrent and subsequent radiofrequency ablation combined with hepatectomy for hepatocellular carcinomas

Figure 1 Successful radiofrequency ablation (RFA) combined with hepatic resection for multifocal hepatocellular carcinomas (HCCs) in a 74-year-old man. A: Contrast-enhanced transverse helical CT scan obtained during the arterial phase before treatment shows two HCCs in the both hepatic lobes. There are 11.0-cm-diameter HCC (white arrows) in left lateral segment and 1.1-cm-diameter HCC (black arrow) in liver segment 7; B: Ferucarbotran-enhanced T2-weighted fast spin echo MR image shows another 1.5-cm-diameter HCC (long white arrow) in liver segment 4. He underwent resection for a large tumor and concurrent RFA for two small tumors; C. Contrast-enhanced transverse helical CT scan obtained 1 mo after combined hepatectomy and RFA shows two round ablation zones (arrows) of low attenuation that suggests technical success of ablation. At 4 mo after treatment, multiple metastatic tumors were found in the both lungs (not shown).
