Spontaneous Carotid Artery Dissection Presenting as Trigeminal Neuralgia in the Emergency Department

INTRODUCTION: Carotid artery dissection (CAD) is a critical diagnosis in the emergency department (ED). Trigeminal neuralgia, while not uncommon, may cause the patient significant discomfort but generally is not attributed to severe morbidity and mortality. CASE REPORT: We present a case of spontaneous CAD presenting with the classic intermittent “lightning-like” jaw and head pain suggestive of trigeminal neuralgia that was ultimately diagnosed utilizing computed tomography angiogram after multiple visits to the ED. DISCUSSION: Coincidentally the patient had been started on anticoagulation a few days prior and no additional intervention was required. CONCLUSION: This case report discusses current recommendations for diagnosis, treatment, and long-term prognosis of CAD.
