a The T1-weighted image (T1WI) shows hepatomegaly, a non-uniform intensity of liver parenchyma with a patchy and nodular low-signal intensity of the liver. b The T2-weighted image (T2WI) shows a non-uniform signal intensity of liver parenchyma with a patchy and nodular high-signal intensity of the liver and ascites. c Arterial phase contrast-enhanced MRI scan shows heterogeneous enhancement of liver parenchyma. d Portal phase contrast-enhanced MRI scan shows a significant heterogeneous enhancement of liver parenchyma with patchy and nodular lesions with decreased enhancement. e HBP of gadoxetic acid-enhanced MRI shows the signal intensity of liver parenchyma is slightly decreased and accompanied by the nodular lesions with lower-signal intensity. f The hematoxylin-eosin (HE) staining at × 200 magnification shows hepatocyte edema and significant hepatic sinus expansion, which is confirmed to be SOS
