Abstract
Vocal cord palsy (VCP) can be caused by laryngeal and extra-laryngeal pathologies affecting the recurrent laryngeal nerves (RLNs). Many cases of left VCP related to cardiovascular pathologies have been documented. However, right VCP associated with cardiovocal (Ortner) syndrome is an atypical and rare presentation. A case of right VCP caused by a right aortic arch (RAA) and Kommerell diverticulum (KD), diagnosed on CT angiography, and its association with the variant course of the right RLN, is described. CONTRIBUTION: This case report highlights the rarity of cardiovocal syndrome causing a right VCP and the association of a RAA with the variant course of the right RLN hooking around the RAA in place of the right subclavian artery.
