Two patients with left recurrent laryngeal nerve paralysis in association with pulmonary artery hypertension are described. One had primary pulmonary hypertension and the other had patent ductus arteriosus. The greatly dilated pulmonary artery in these patients resulted in compression of the left recurrent laryngeal nerve and produced a cardiovocal (Ortner's) syndrome. The pathogenesis of the vocal cord palsy was documented by cross-sectional computed tomography.
In conclusion, computed tomography is of great help in differentiating this syndrome from other diseases such as mediastinal mass or lymphadenopathy whenever hoarseness is complicated by pulmonary hypertension.
