title: Primary Budd-Chiari syndrome due to complex venous anomalies.
abstract: A 35-year-old woman with clinical features of Budd-Chiari syndrome is presented. Abdominal ultrasonography, computed tomography, and venography disclosed that the venous congestion in this patient resulted from complex venous anomalies including azygos-hemiazygos continuation, absent superior hepatic veins, and retroaortic transposition of the left renal vein.
