Congenital agenesis of the right pulmonary artery.
A 44-year-old woman with recurrent pulmonary infections developed severe hemoptysis. Chest radiography revealed a hypoplastic right lung. Absence of the right pulmonary artery, a very rare congenital anomaly, was demonstrated by computed tomography and cardiac catheterization. Severe pulmonary hypertension in the contralateral lung precluded right pneumonectomy but percutaneous embolization of a large systemic arterial collateral to the right lung provided palliative relief of hemoptysis.
