Abstract:
Ortner's syndrome (cardiovocal syndrome) is a rare cause of unilateral vocal cord paralysis that results from compression of the left recurrent laryngeal nerve by enlarged vascular structures. Most commonly, it is caused by an enlarged left atrium, but other rare causes include ascending aortic aneurysm or pulmonary artery aneurysm. Although very rarely encountered nowadays, bilharziasis is still one of the main causes of pulmonary artery aneurysm in endemic areas. Hereby, we report a case of Ortner's syndrome due to a large pulmonary artery aneurysm in a woman with history of bilharziasis.
