Hoarseness is a common clinical problem which may also imply an initial manifestation of serious disease. Lesions affecting the recurrent laryngeal nerve will result in vocal cord paralysis and hoarseness. Malignancy accounts for most of the extralaryngeal causes of vocal cord paralysis, but other causes could include even cardiovascular disease. Cardiovocal syndrome is a left recurrent laryngeal nerve palsy caused by cardiovascular disease. Hoarseness may be the only presentation of thoracic aortic aneurysm or painless dissection. Vocal cord function can return after successful repair. We report a 72 year-old man who had hoarseness for 1 month. Dissecting aneurysms of the aortic arch and thoracic aorta were found. An operation was performed, but the patient had difficulty weaning from the ventilator and died of sepsis.
