A. Chest radiographs show a tortuous abnormal vascular structure (arrows) at the left parahilar area. B. Venous-phase image in the main pulmonary angiogram shows a tortuous and dilated abnormal vessel in the left parahilar area, which drains into the left atrium through an anomalous pulmonary vein (arrows). The right superior and inferior pulmonary veins drain normally into the left atrium (arrowheads). C. Early arterial-phase image of the left upper lobar selective pulmonary angiogram shows no early draining vein. D. An anomalous venous structure (arrows) is seen in the late-venous phase.
