Eagle Syndrome: A Wide Spectrum of Clinical and Neuroradiological Findings From Cervico-Facial Pain to Cerebral Ischemia

Eagle syndrome (ES) is a rare symptomatic condition generally caused by abnormal elongation of the styloid process or calcification of stylo-hyoid ligament.Patients with ES typically present a variety of symptoms, which range from mild discomfort to acute neurologic and referred pain in head-and-neck region.Eagle syndrome could be identified through physical examination but often goes undetected in the absence of imaging studies.Although uncommon, it should be considered in the differential diagnosis in patients with cervico-facial pain.The authors report 3 cases with clinical evidence of ES, including both neurologic and vascular patterns, with a clinical and radiological diagnosis.The authors also propose a brief review of its main clinical presentations, diagnostic studies, and part of treatment options of the syndrome.
