title: Hemiazygos continuation of a left inferior vena cava draining into the right atrium via persistent left superior vena cava: demonstration by helical computed tomography.
abstract: We report an unusual case of hemiazygos continuation of a left inferior vena cava draining into the right atrium via the persistent superior vena cava. Spiral computed tomography (CT) showed the course and the flow direction of this vena caval anomaly in a real-time manner, obviating conventional venography.
