Diagnosis With Brief Discussion
- Diagnosis
- Ortner's Syndrome
- Radiologic Findings
- Chest radiograph shows a well-defined bulging soft tissue lesion in the left suprahilar area.
Neck CT demonstrates left vocal cord palsy.
CT angiography of the aorta reveals a saccular aneurysm with mural thrombus at the left lateral aspect of the aortic arch.
- Brief Review
- Ortner's Syndrome is a rare clinical entity, first described in 1897. It describes left recurrent laryngeal nerve palsy resulting from identifiable cardiovascular disease.
Left recurrent laryngeal nerve arises from the vagus nerve on the left side of the aortic arch. This nerve curves beneath the aorta on the outer side of ligamentum arteriosum and ascends to the groove between the esophagus and the trachea. It continues along this groove to supply all the muscles acting on the left vocal cord, except the cricothyroid muscle, which is innervated by the superior laryngeal nerve.
In this syndrome, the left recurrent laryngeal nerve is thought to be injured due to compression caused by changes in the anatomy of the heart or great vessels. Cardiovascular disease is an unusual cause of vocal cord palsy, and for this reason it is also known as cardiovocal syndrome. Various underlying causes include left ventricular failure, atrial septal defect, Eisenmenger syndrome, mitral valve prolapse, primary pulmonary hypertension, aortic aneurysm, and aortic dissection.
