Abstract
Background. We report a rare case of hemoptysis from a ruptured bronchial arterial aneurysm without lung disease. Case. A 54-year-old man was admitted to our hospital because of hemoptysis. Chest X-ray showed consolidation in the right upper lung field. Chest CT also revealed consolidation and ground glass opacity in the right S^1 and S^2. Since bronchoscopic therapy was not effective, we performed bronchial arteriography. Bronchial arteriography demonstrated a small aneurysm of the right bronchial artery. Flow into the bronchus from the aneurysm was observed. We performed bronchial arteial embolization. After successful embolization, the patient had no hemoptysis. Conclusion. Bronchial arteriography and embolization were very useful for the diagnosis and the treatment of bronchial arterial aneurysm.
