Imaging characteristics of a histologically proven HA in a 34-year-old woman with gadoxetic acid-enhanced MRI. The lesion is hyperintense on the late arterial phase contrast-enhanced T1w image (T1w dur, D), contains a significant amount of fat as demonstrated by dropout of signal on opposed phase imaging (C), and is slightly hyperintense on T2w imaging (A). Note the hypointensity of the lesion on delayed T1w hepatobiliary phase images at 20 minutes (T1w 20min, F) relative to the adjacent liver.
