Abstract:
Purpose To compare the MRI features of hepatic sinusoidal obstruction syndrome(HSOS)and Budd-Chiari syndrome(BCS).Materials and Methods A total of 12 cases of HSOS and 12 cases of BCS diagnosed with liver biopsy or liver transplantation disease or digital subtraction angiography were retrospectively collected from April 2016 to November 2023 in Beijing Friendship Hospital,Capital Medical University.The clinical and MRI features of the two groups were analyzed,and the characteristic clinical and MRI features were summarized.Results The glutamic-oxaloacetic transaminase,total bilirubin and direct bilirubin in HSOS patients were significantly higher than those in BCS group,while albumin was significantly lower than that in BCS group,the difference was statistically significant(Z=-3.407,-2.078,-2.425,-2.252,all P<0.05).Of the 12 HSOS patients,ten patients with HSOS had a history of taking hebel medicine(gynura segetum),six patients with HSOS showed the second portal of liver characteristic trifolium-like enhancement,BCS features did not appear.Of the 12 BCS patients,ten had main portal vein widening,ten spleen enlargement,ten accessory hepatic vein,eight transverse hepatic vein,eleven perihepatic lateral branch and seven paravertebral varicose veins.In HSOS and BCS patients,the uneven proportion of liver parenchymal signals was identified by MRI plain scan(12 cases,10 cases,respectively),and the proportion of liver parenchymal signal mottle-like enhancement was also demonstrated in portal and delayed phases(12 cases,12 cases,respectively).Conclusion The characteristic MRI signs are helpful for the diagnosis of HSOS and BCS,and the history of taking hebel medicine(gynura segetum)is helpful for the differentiation of the two diseases.
