Figure 2 Characteristics of benign and malignant liver masses. A: A distinctly demarcated hyperechoic lesion consistent with a benign hemangioma. B: A liver lesion with both iso/hypoechoic parts peripherally (outlined in orange in inset) and central hyperechoic parts suggestive of malignancy. C: A hypoechoic mass exhibiting post-acoustic enhancement (outlined in orange in inset) as frequently seen in malignancy. D: A hypoechoic, poorly demarcated mass distorting adjacent strictures (orange arrows and brackets in inset) suggestive of malignancy.
