Abstract:
Focal nodular hyperplasia（FNH），which usually occurs in the context of a normal liver，is the second most common benign hepatic lesion，with typical imaging manifestations of hypointensification in the portal and delayed phases of enhancement scans，and a stellate scar visible in the center. Budd-Chiari syndrome（BCS）is a rare hepatic vascular disease defined as obstruction of the hepatic venous outflow tract and is categorized as primary and secondary. The patient was a 20-year-old female，who came to the First Hospital of Jilin University for routine physical examination，without no obvious discomfort，no definite abnormality on physical examination，previous physical fitness，no abnormality on laboratory tests. Ultrasound（contrast-enhanced ultrasound）and enhanced CT suggested：FNH；BCS. In this case，BCS was due to compression of the right hepatic vein and inferior vena cava by a giant FNH，the patient refused to undergo invasive treatment due to the presence of an effective collateral circulation of the inferior vena cava with intrahepatic return and the absence of portal hypertension and other manifestations. Ultrasound and contrast-enhanced ultrasound can be used for real-time and dynamic imaging to observe intra- and extra-hepatic vascular obstruction and hemodynamic changes，with typical imaging manifestations of FNH and BCS，providing strong evidence for the diagnosis of this disease.
