title: Meandering pulmonary veins mimicking arteriovenous malformation.
abstract: We report a case of preoperative incidental finding in a 34-year-old man with a significant aortic insufficiency. Preoperative chest x-ray was suspicious for arteriovenous malformation in the right lung. Chest CT angiography discovered an anomalous course of the left superior pulmonary vein crossing the mediastinum to the contralateral hemithorax, joining the right superior pulmonary vein before entering the right inferior pulmonary vein and forming a common trunk of right inferior pulmonary vein.
