Fig. 6. —Hepatocellular carcinoma mimicking hemangioma in 66-year-old man with liver cirrhosis. Baseline gray-scale sonogram (upper left) shows hyperechoic mass (arrow) at dome of left lateral segment. Note coarse echogenicity and surface undulation of liver, suggesting liver cirrhosis. This lesion was believed to be indeterminate by both radiologists. They recommended further imaging for lesion characterization. Serial contrast-enhanced agent detection images obtained 27 sec (upper right), 36 sec (lower left), and 3 min (lower right) after injection depict peripheral nodular enhancement, which is more apparent as time passes. During interpretation of contrast-enhanced sonograms, this lesion was assigned as probably benign and characterized as hemangioma by both radiologists; however, one of radiologists recommended further workup for lesion characterization.
