[SUNCT syndrome--case report and review of the literature].

The SUNCT syndrome is a recently described headache disorder characterised by shortlasting, unilateral headache attacks with conjunctival injection and tearing. Our report presents a further case and compares the findings in our patient with those in the cases described earlier. In addition, we review the literature and discuss possible aetiological and pathogenetic factors as well as the differential diagnosis of SUNCT syndrome, trigeminal neuralgia and cluster headache syndromes.
