title: Early diagnosis of Budd-Chiari syndrome by computed tomography and ultrasonography: report of five cases.
abstract: In 5 patients with Budd-Chiari syndrome, computed tomography after intravenous bolus injection of iodinated contrast agents demonstrated images not previously seen in other diseases. The images are compatible with stagnation of contrast material at the periphery of the liver. In 3 of the 5 cases, grey-scale ultrasonography failed to document the normal hepatic veins draining into the inferior caval vein, but showed an intrahepatic network of comma-shaped venous structures. It is proposed that these two noninvasive approaches can help in establishing an early diagnosis.
