Budd-Chiari Syndrome with Multiple Thrombi due to a Familial Arg42Ser Mutation in the Protein C Gene
Imaging studies. (a) Carotid ultrasonography shows a thrombus of the right internal jugular vein indicated by the arrow. Blood flow in the right internal jugular vein was maintained. (b) Abdominal MRI first imaging employing steady state acuisition (FIESTA) reveals a high-intensity signal emanating from the intrahepatic portion of the inferior vena cava (arrow), which suggested thrombus. (c) Thoracic CT during injection of contrast medium reveals right pleural effusion and dilatation of an azygos vein at the arrows. (d) Abdominal Doppler ultrasonography shows complete patency (arrow) and no ectopia of the stent. This image was acquired 16 months after the patient was admitted.
