Figure 3 61-year-old man with a history of transarterial chemoembolization for hepatocellular carcinoma. A 6-mm recurrent hepatocellular carcinoma in segment 8 of the liver is seen by magnetic resonance imaging (MRI). The tiny nodule (arrow) shows arterial enhancement (A) and high signal intensity on diffusion-weighted image (B). Unfortunately, there was no mention of the lesion in the radiologic report, and the tumor was unintentionally diagnosed late. At follow up MRI obtained 6 mo later, the lesion (arrow) had increased in size and measured up to 22 mm on arterial phase (C) and diffusion-weighted image (D). Given that the lesion had irregular margins and showed rapid growth, the tumor might have aggressive tumor biology.
