Abstract Patients with internal carotid artery dissection (ICAD) usually report headache, neck pain, Horner's syndrome, and ischemic stroke. Because the posterior cranial nerve is involved, some patients may show different forms of posterior cranial nerve paralysis. There have been no reports of patients with ICAD showing repeated hiccups. Here, to help clinicians identify ICAD early and gain a better understanding of the atypical manifestations of the disease, we report an atypical case of recurrent hiccup symptoms caused by ICAD.
