Hepatic sinusoidal obstruction syndrome (HSOS) can be easily missed or misdiagnosed as Budd-Chiari syndrome in clinical practice. The authors displayed the imaging pictures of 1 patient with HSOS and made a brief description of typical imaging features, underlying pathophysiological mechanisms, and differential diagnoses of HSOS, with the hope of improving the understanding of HSOS and reducing the rates of leak diagnosis or misdiagnosis.
