Spectrum of imaging in Budd Chiari syndrome

Area of Science:

• Hepatology
• Vascular Medicine
• Radiology

Background:

• Budd Chiari syndrome is a rare condition characterized by obstruction of hepatic venous outflow.
• It presents with significant morbidity and mortality, necessitating prompt diagnosis and management.
• The diffuse nature of the syndrome can render biopsy findings inconclusive.

Purpose of the Study:

• To illustrate the diverse imaging findings associated with Budd Chiari syndrome.
• To emphasize the importance of imaging in the definitive diagnosis of Budd Chiari syndrome.
• To provide a comprehensive pictorial essay of the imaging spectrum.

Main Methods:

• Review of imaging studies in patients diagnosed with Budd Chiari syndrome.
• Correlation of imaging findings with clinical presentation and outcomes.
• Discussion of various imaging modalities including ultrasound, CT, and MRI.

Main Results:

• Obstruction can occur at various levels, from hepatic venules to the inferior vena cava-right atrium junction.
• Characteristic imaging findings include hepatic vein stenosis or atresia, collateral vessel formation, and caudate lobe hypertrophy.
• Imaging demonstrates the extent and location of venous obstruction, aiding in treatment planning.

Conclusions:

• Early and accurate diagnosis of Budd Chiari syndrome is critical for improving patient outcomes.
• Imaging is essential for the definitive diagnosis, especially when biopsy results are equivocal.
• Understanding the imaging spectrum is key for radiologists and clinicians managing this complex disorder.
