[A case of Ortner syndrome caused by primary pulmonary hypertension].

Left vocal cord palsy is a rare complication of pulmonary hypertension (also known as Ortner syndrome). Here we report a case of a patient with Ortner syndrome caused by primary pulmonary hypertension (PPH). The patient was a 28-year-old woman, who complained of persistent hoarseness and dyspnea on effort. A left vocal cord palsy, as well as PPH, was diagnosed, suggesting that pulmonary artery dilatation associated with PPH led to left recurrent laryngeal nerve palsy. This case suggests that PPH should be suspected in any case with unexplained left vocal cord palsy.
