The first reported case of left vocal cord paralysis caused by pulmonary embolization is presented. The apparent mechanism was compression of the recurrent laryngeal nerve against the aorta by a dilated, tense pulmonary artery, enlarged as a result of embolic vascular obstruction. Perfusion lung scanning should be a part of the evaluation of patients with paralysis of the left vocal cord, when recurrent pulmonary embolization is a possibility.
