A Case Report: Internal Carotid Artery Dissection Presenting as Hoarseness Secondary to Vocal Cord Palsy

Internal carotid artery (ICA) dissection is a rare cause of a cranial nerve X palsy. Patients more commonly present with stroke or transient ischaemic attacks. An undetected and untreated ICA dissection can have serious consequences. Here, the authors present two cases of ICA dissection presenting with isolated vagal nerve palsy presenting with hoarseness. CT scans provided good evidence of ICA in both cases. The patients were treated with antiplatelet agents and made a good recovery with complete resolution of symptoms.
