Secondary SUNCT syndrome caused by dorsolateral medullary infarction

Short-lasting unilateral neuralgiform headaches with conjunctival injection and tearing (SUNCT) is a rare headache syndrome which belongs to trigeminal autonomic cephalalgias. Though the majority of SUNCT syndrome is idiopathic, more and more cases of secondary SUNCT syndrome have been reported recently. In this study, we present a case of symptomatic SUNCT syndrome caused by acute dorsolateral medullary infarction which was verified by brain MRI(magnetic resonance imaging). Up to now, there is not absolutely effective treatment for SUNCT syndrome. However, in our case, SUNCT was completely resolved after conventional treatment for cerebral infarction without specific drug intervention.
