We reported that a 68-year-old man presented to the ENT outpatient department complaining of hoarseness for more than 10 months. Clinical exam identified left vocal palsy in the paramedian position and atrophic vocal folds were noted. Chest radiography revealed a large bulging contour overlying aorta and left hilar shadow. Aortic aneurysm was proved by CT scanning. Contrast-enhanced chest computed tomography for further evaluation showed a broad-based aortic aneurysm at proximal descending aorta, projecting anterolaterally. Cardiovocal syndrome was proved. The syndrome is a rare clinical presentation. While a patient with unilateral vocal palsy is encountered, one might keep in mind the possibility of cardiovocal syndrome especially in an adult who had a cardiovascular disease.
