Left brachiocephalic vein stenosis and infectious aortitis: two unusual causes of Ortner's syndrome.

Ortner's syndrome (also known as cardiovocal syndrome) is defined as hoarseness due to compression of the left recurrent laryngeal nerve by an enlarged left atrium or enlarged thoracic vessels. We describe two cases of Ortner's syndrome with an unusual underlying vascular pathology. In the first patient, Ortner's syndrome was a consequence of left brachiocephalic vein stenosis resulting in collateral circulation filling the aorto-pulmonary window. The second patient developed a thoracic aortic aneurysm due infectious aortitis. Both patients required careful scrutiny in differential diagnosis because of their complex past medical history and concomitant diseases.
