Right vocal cord paralysis in our present case was diagnosed on clinical and radiological examination which is precipitated by an anomalous right aortic arch with diverticulum. This is a very uncommon vascular etiology of hoarseness and is extremely rare. Because of this rarity, the practicing otolaryngologist may miss this finding while evaluating a case of idiopathic right vocal cord paralysis. Thus, the authors feel that idiopathic or unexplained right vocal cord paralysis should be routinely investigated with a CT or MRI of neck and chest with or without contrast to avoid such shortcomings. There is only one such case of right vocal cord paralysis by right aortic which has been reported earlier in literature.
