Paroxysmal short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT) is a rare headache syndrome that was first described in 1989. SUNCT syndrome is charac- terized by short-lasting(usually 5-250sec), unilateral moderate to severe orbital or peri-ocular pain accom- panied by ipsilateral conjunctival injection, lacrimination, and nasal obstruction or rhinorrhea. The pain is resistant to various medications, but topiramate, gabapentin, and lamotrigine were effective in some reports. We report a 62 year-old man who was diagnosed as SUNCT syndrome, whose symptoms were effecti- vely controlled by gabapentin with β-blocker. Korean Journal of Headache 5(2):143-147, 2004
