Internal Carotid Artery Dissection Presenting With Dysgeusia, Horner Syndrome, and Hypesthesia of the Fifth Cranial Nerve: A Case Report.

Carotid artery dissection (CAD) is a significant cause of ischemic stroke. Early recognition and treatment of CAD is important to prevent accompanying cerebral ischemia. This case report presents an atypical clinical presentation of CAD and emphasizes the diagnostic challenge for emergency physicians. A 54-year-old woman presented to the emergency department with a bilateral headache of 4 days' duration, hypesthesia of the left fifth cranial nerve, dysgeusia, and partial Horner syndrome on the left side. Magnetic resonance angiography showed a left-sided CAD without any signs of cerebral ischemic events. Antiplatelet therapy with clopidogrel was started, and the patient did not show any deterioration in the weeks thereafter. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: CAD can present with different combinations of cranial nerve palsies and should be in the differential diagnosis of dysgeusia and hypesthesia of the trigeminal nerve. Early recognition of CAD can be challenging in patients with rare cranial nerve involvement, but early treatment is crucial to prevent cerebral ischemic events. Copyright © 2019 Elsevier Inc.
