A computed tomography (CT) scan incidentally presented a homogeneously enhanced tumor, 3.1 cm in diameter, in the posterior mediastinum. Venography by the right brachial vein showed retrograde flow from the superior vena cava to azygos vein in the early phase. In the delayed phase, pooling of contrast medium in the tumor was observed. Based on the above findings, the tumor was diagnosed as an azygos vein aneurysm. She underwent aneurysm resection under video-assisted thoracic surgery (VATS) due to the risk of pulmonary thrombosis and rupture of the aneurysm. Initially, the proximal end of the azygos vein was resected due to the risk of pulmonary embolism, and, then, three intercostal veins and the distal end of the azygos vein were resected. Finally, after complete blockage of the azygos vein, the aneurysm was resected. The patient followed an uneventful postoperative course, and was discharged on the 10th postoperative day without complication., 金沢大学医薬保健研究域医学系},
