A 39-year-old man with SOS caused by Tu san qi. a Normal CT scan shows non-uniform density of the liver parenchyma, hepatomegaly, and medium to a large amount of ascites. b Arterial phase contrast-enhanced CT scan shows non-uniform enhancement of hepatic parenchyma. c–e Portal phase contrast-enhanced CT scan shows patchy low-density lesions with a non-uniform decrease of hepatic parenchyma enhancement (the CT value of the liver is lower than that of the spleen), portal hypertension combined with collateral circulation development, gallbladder wall edema, and edema around the portal vein. f The hematoxylin-eosin (HE) staining at × 200 magnification shows expansion and congestion around the central hepatic vein and hepatic sinus, hepatocyte edema, and mild central venous fibrosis, which is confirmed to be SOS
