A 74-year-old man was admitted to hospital because of sudden onset of chest pain and dyspnea. The chest X-ray film revealed left hemothorax. Chest computed tomographic (CT) scan confirmed left hemothorax and excluded the possibility of aortic dissection and aneurysm of the aorta. ⋯ Three-dimensional (3D) -CT confirmed a definitive diagnosis of ruptured bronchial artery aneurysm. Bronchial artery embolization (BAE) was performed. We report a case of ruptured bronchial artery aneurysm complicated by life-threatening massive bleeding and resembling a clinical picture of aortic dissection.
