Bronchial artery aneurysm is a rare condition. Rupture of bronchial artery aneurysm can cause a critical hemorrhage. We report a case of ruptured bronchial artery aneurysm mimicking a clinical picture of aortic dissection with right hemothorax. The patient was treated with a combination of an aortic stent-graft and arterial embolization. Recovery was uneventful and the patient's follow-up result in 1 year was well. Combination treatment is feasible and accurate for ruptured bronchial artery aneurysm. The present study is among the few in which an aortic stent-graft has been used for a bronchial artery aneurysm.
