Complete remission of advanced hepatocellular carcinoma by radiofrequency ablation after sorafenib therapy

Figure 1 Arterial phase scans of contrast enhanced multiphase computed tomogram of abdomen. A: Baseline abdominal computed tomogram (CT) scan showed 12.5 cm sized enhancing mass in segment 8 with tumor thrombus in middle, right hepatic vein extending to intrahepatic inferior vena cava; B: The size of tumor decreased to 4.8 cm with 2.7 cm sized enhancing nodule in tumor in 6 mo-follow-up CT scans; C: The tumor size further decreased to 3.0 cm with 1.5 cm sized enhancing nodule within tumor in 12 mo-follow-up CT scans with resolution of tumor thrombus in hepatic vein and portal vein. D: There was no arterial enhancing viable portion in ablated tumor in abdominal CT scans 6 mo after radiofrequency ablation.
