ABSTRACT

Short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms (SUNA) is a rare primary headache syndrome. The diagnostic criteria include attacks of unilateral orbital, supraorbital or temporal stabbing pain accompanied by one of the following: conjunctival injection and/or tearing, nasal congestion and/or rhinorrhea, and eyelid edema. The duration of pain is 2 seconds to 10 minutes, and the frequency of attacks is described as once a day or more. The etiology and pathology of SUNA has yet to be documented. We report an 18-year-old man with SUNA. Lomerizine hydrochloride which is used as a preventive medicine for migraine, improved his headaches.
