A 48-year-old woman with focal SOS (arrows) developed by chemotherapy after hepatectomy. a, b A nodular lesion in liver segment III with low-signal intensity on the T1-weighted image (T1WI) and high-signal intensity on the T2-weighted image (T2WI). c Arterial phase contrast-enhanced MRI scan shows a nodular lesion in liver segment III with mild peripheral enhancement. d Portal phase contrast-enhanced MRI scan shows the nodular lesion with apparent, uniform, and persistent enhancement. e HBP of gadoxetic acid-enhanced MRI shows the nodular lesion with a low-signal intensity at the center and high-signal intensity around it, which presents as “focal nodular hyperplasia” like lesion. f The diffusion-weighted imaging (DWI) shows an apparent limited diffusion
