Left vocal cord paralysis in association with patent ductus arteriosus is unusual. We report a patient with long-standing patent ductus arteriosus (PDA) in whom CT studies obtained before and after paralysis developed showed an interval increase in size of the pulmonary trunk. The pathogenesis of left vocal cord paralysis in association with long-standing PDA is discussed.
