Eagle's Syndrome, from clinical presentation to diagnosis and surgical treatment: a case report.

Eagle's syndrome is a condition associated with the elongation of the styloid process or calcification of the stylohyoid ligament, clinically characterised by throat and neck pain, radiating into the ear. In this report, we describe the case of a 60-year-old woman who presented with a severe unilateral trigeminal and glossopharyngeal neuralgia. The patient was subjected to conservative therapy for four months and did not report improvement of the symptoms. After several consultations with different physicians, a diagnosis was accomplished by radiological investigation (multidetector computer tomography with multi-planar reconstructions and 3D volumetric reconstructions). Surgical styloidectomy was performed, with subsequent sudden remission of symptoms. Eagle's syndrome represents a commonly unrecognised nosological entity, clinically characterised by non-specific cranio-facial pain. Differential diagnosis includes glossopharyngeal and trigeminal neuralgia, temporal arteritis, migraine, myofascial pain dysfunction and cervical arthritis. Eagle's syndrome should always be suspected, mostly in adult women when the pain is unilateral and not responsive to painkillers.
