Successful transcatheter arterial embolization in an asymptomatic patient with primary racemose hemangioma of the bronchial artery

An asymptomatic 70-year-old woman presented with a nodular lesion overlapping the pulmonary artery at the right hilar region on a chest X-ray. Bronchial arteriography revealed an aneurysmal dilation of the long segment of the right bronchial artery and a shunt from the right bronchial artery to the right lower pulmonary artery. She was diagnosed with primary racemose hemangioma of the bronchial artery (RHBA). Considering the risk of hemoptysis, we performed a bronchial arterial embolization (BAE) using coils and N-butyl-2-cyanoacrylate. She had no complication after the BAE and no recurrences of hemoptysis at the 36-month follow-up. RHBA should be considered in case of aneurysmal dilation in the long segment of the bronchial artery, and BAE should be considered as a treatment strategy despite the absence of symptoms.
