Figure 5. Adenoma. 34-year-old woman with a long continuous history of oral contraceptive use. a greyscale image shows a superficial focal hypoechoic mass (arrows) in a fatty liver (A); an early arterial phase (AP) image at 12 s shows peripheral irregular vessels (B); at the peak of AP enhancement, 20 s, the mass is uniformly hyperenhanced (C); at 3 min, the mass shows sustained enhancement such that it is still slightly brighter than the adjacent enhanced liver parenchyma (D)
