Vocal cord paraysis is a clinical finding that can occure due to intralaryngeal or extralaryngeal payhologies. Left vocal cord paralysis secondary to cardiovascular causes is called Ortner Syndrome (which is also called Cardiovocal Syndrome). It was described by Ortner in 1897 on a case with mitral stenosis. The various underlying conditions includes septal defect, mitral valve prolapse and aortic aneurysm. Ortner syndrome due to spontaneus ductus arteriosus aneurysm is quite rare. In this article, we are representing a 67 year old male, who has hoarseness for a year, with left vocal cord paralysis on physical examination and a chest CT establishing an aneurysm of ductus arteriosus.
