[A specific form of headache with neuralgia-like manifestations (SUNCT-syndrome)]

A recently described SUNCT is a rare head ache syndrome characterized by shortlasting, unilateral, neuralgia-like headache attack with conjunctival injection and tearing; 26 cases of SUNCT-syndrome have been reported in medical literature. The authors observed the described symptoms in 3 cases (among 86 patients with trigeminal paroxysmal manifestations). Clinical features of SUNCT-syndrome are presented. In addition, the authors discuss possible etiologic factors and treatment as well as a differential diagnosis of SUNCT-syndrome, from trigeminal neuralgia, cluster headache, chronic paroxysmal hemicrania and combined syndromes.
