Characterization of focal hepatic lesions with contrast-enhanced C-cube gray scale ultrasonography

Figure 6 A 51-year-old female with angiomyolipoma. A. Subcostal section of precontrast conventional sonography exhibits a hyperechogenic lesion of 7.3 cm in diameter. B-D. Contrast-enhanced C-cube gray scale sonography at 54 s (B) and 110 s (C) after injection of Levovist shows that intranodular signals enhance earlier than the liver parenchyma with an inhomogenous enhance-ment pattern, and enhancement decreases in the delayed phase (206 s, D). E. Photomicrography shows defuse sheets of adipocytes and muscle cells adjacent to the noncirrhotic liver tissue, presenting a typical appearance of angiomyolipoma (HE 400).
