Value of radiofrequency ablation in the treatment of hepatocellular carcinoma

Figure 1 Radiofrequency ablation combined with right hemihepatectomy for multifocal hepatocellular carcinoma in a 69-year-old woman. A: Preoperative contrast-enhanced transverse helical computed tomography (CT) scan obtained during the venous phase shows one small hepatocellular carcinoma (HCC) 1.4 cm diameter in the left hepatic lobe (black arrow); B: An HCC 7.0 cm in diameter (black arrow) is present in the right hepatic lobe; C: Contrast-enhanced CT showed round ablation zones (white arrow) 6 mo after resection of the large tumor and concurrent radiofrequency ablation for the small tumor. Tumor recurrence was not found in the remnant liver.
