Abstract
Budd-Chiari syndrome (BCS) is defined by clinical and laboratory signs associated with partial or complete impairment of hepatic venous drainage in the absence of right heart failure or constrictive pericarditis. Primary BCS is the most frequent type and is a complication of hypercoagulable states, in particular myeloproliferative neoplasms. Secondary BCS involves tumor invasion or extrinsic compression. Most patients present with chronic BCS including a non-cirrhotic, dysmorphic, chronic liver disease with various degrees of fibrosis deposition. Acute BCS is rare, and patients present with hepatomegaly, ascites, and hepatic insufficiency. The diagnosis is based on imaging. Imaging features include (1) direct signs, in particular occlusion or compression of the hepatic veins and/or the inferior vena cava and venous collaterals and (2) indirect signs, in particular morphological changes in the liver with hypertrophy of the caudate lobe and delayed nodule formation. Ultrasound and magnetic resonance imaging are the gold standard for diagnosis. The aim of this review is to provide an overview of the role of imaging in the diagnosis of BCS.
