From: Thoracoscopic approach to the resection of idiopathic azygos vein aneurysm: a case report
A, B: Chest computed tomography showed a soft-tissue mass in the right posterior mediastinum. Enhanced computed tomography scanning showed the mass with similar enhancement to the aortain(white arrow), and the internal density was uneven. C, D: Coronary reconstruction showed that the mass was connected with the azygos vein(white arrow). E: Thoracoscopic surgery revealed a mass arising from the azygos venous arch; there was light adhesion. F: The venomous mass was completely removed
