Role of hepatectomy for recurrent or initially unresectable hepatocellular carcinoma

Figure 1 Recurrent hepatocellular carcinoma adjacent to a radiofrequency ablation scar. A: Computed tomography showing the tumor with unclear borders with arterial enhancement (arrow) adjacent to the scar (arrowhead); B: Cut surface of the resected specimen showing the recurrent tumor (arrow) and radiofrequency ablation scar (arrowhead).

Figure 2 Multinodular hepatocellular carcinomas. Transarterial chemoembolization achieved complete response in one tumor in segment IV with accumulation of lipiodol showing no arterial enhancement in contrast to the other tumor in segments VI and VII that was enhanced in the arterial phase (A) and washed out in the portal phase (B).
