Jugular Foramen Syndrome with Miosis: A Sign of Internal Carotid Artery Dissection

Abstract

We describe a case of left extra and intracranial internal carotid artery dissection in a 59-year-old man who presented with the clinical features of left jugular foramen syndrome (dysphonia, dysphagia, ageusia, paralysis of the sternocleidomastoid muscle) and ipsilateral miosis with acute onset, worsening in the first 24 hours and spontaneous remission over the next thirty days. The patient was investigated by computed tomography magnetic resonance and digital angiography and received conservative treatment. The clinical aspects are discussed, emphasizing the major role of magnetic resonance in the diagnosis of the syndrome.
