[A case of asymptomatic racemose hemangioma treated by bronchial artery embolization].
A 69-year-old man had an abnormal shadow on chest X-ray and bronchoscopic examination showed that left B4 was completely occluded by a tumor. A non-pulsatile polypoid nodule was also found in right B'. The tumor in the left B4 was diagnosed as carcinoid, but the nodule in right B' was suspected to be hemangioma and biopsy was not performed. Bronchial arteriography revealed hypervascularization with dilated vessels distributing to the lingular lobe and convoluted and a dilated bronchial artery extending to the right upper lobe. From these findings, we diagnosed racemose hemangioma of the bronchial artery of the right upper lobe. After bronchial artery embolization of the right and left bronchial arteries, he underwent segmentectomy of the lingula and was discharged without complications. Two months after the operation, bronchoscopic examination showed that the racemose hemangioma had shrunk and the swelling in the surrounding mucosa had decreased. If a submucosal small nodule is observed during bronchoscopy, biopsy should be performed after bronchial arteriography, and if the nodule is diagnosed as racemose hemangioma, bronchial artery embolization should be performed.
