Figure 2

Abdominal ultrasonography (USG) and CT findings: (a) USG shows a 3 × 3cm slightly hypoisoechoic hepatic lesion in left lateral lobe with slightly unclear borders and blood flow signal; (b) plain CT shows that the lesion is lobulated, homogeneous, and isointense compared to surrounding liver parenchyma; (c) enhanced CT shows that hypervascular lesion appears hyperdense with a slightly hypodense central scar in the arterial phase (arrows); (d) in the portal venous phase the lesion is isodense without signs of central scar.
