Management of hepatocellular carcinoma: Enlightening the gray zones

Figure 1 Typical hepatocellular carcinoma at magnetic resonance imaging: contrast enhancement in arterial phase (A) and washout in venous (B)/late (C) phase.

Figure 2 Multi-nodular hepatocellular carcinoma. A: Basal and arterial computed tomography (CT) phase; B: Venous and late CT phase.

Figure 3 A new typical hepatocellular carcinoma found at computed tomography during follow up another hepatocellular carcinoma treated with radiofrequency ablation (central lesion). Note that also in the treated lesion there is a marginal area of vital hepatocellular carcinoma.
