A 69-year-old woman with multiple hepatic hemangiomas. (a) US pre-CEUS showed a hyperechoic lesion (↑) near liver surface and a hypoechoic lesion (▲) near gallbladder. (b) US post-CEUS showed that the lesion (↑) near liver surface became relatively hypoechoic while the echogenicity of the lesion (▲) near gallbladder increased at 8 minutes after contrast agent injection.
