[Bronchial artery embolization can be effective for primary racemose hemangioma].

We report two cases of primary racemose hemangioma in patients with hemoptysis. In the first, a 59-year-old man had a pulsatile polypoid lesion in the bronchus of the lingula; and in the second, a 24-year-old woman had a nodule in the bronchus of the right lower lobe. In both patients, arteriography of the bronchial artery revealed enlargement and convolution of its branches. Primary racemose hemangioma was diagnosed in both patients. The arteriography also revealed a shunt between the pulmonary and bronchial arteries in the woman. Bronchial artery embolization (BAE) was an effective treatment for the hemoptysis. To date, eight months after the embolization, hemoptysis has not recurred. Bronchoscopy and arteriography of the bronchial artery are both useful for diagnosing primary racemose hemangioma. BAE seems to be effective in treating primary racemose hemangioma.
