Jugular foramen schwannoma presenting with glossopharyngeal neuralgia syncope syndrome

Jugular foramen schwannomas are rare skull base tumours which typically have a variable clinical presentation. Glossopharyngeal syncope syndrome is an unusual clinical presentation; in the following case report, it was the sole presentation of an extracranial jugular foramen tumour.

The presentation of a patient with glossopharyngeal neuralgia syncope syndrome is reviewed and the pathophysiology, clinical features and treatment discussed.

A 45-year-old woman presented with unilateral throat pain, bradycardia and hypotension leading to episodes of impaired consciousness when lying on her left side or turning her head to the left. Imaging detected a left-sided extracranial jugular foramen schwannoma. The tumour was excised, and the patient had no more syncopal attacks.

Glossopharyngeal neuralgia syncope syndrome can be the sole presentation of a jugular foramen schwannoma. Although this syndrome may be treated with anti-dysrhythmic drugs, cardiac pacing or nerve section, in the presented patient excision of the jugular foramen schwannoma was successful in preventing further episodes of syncope.
