[A Japanese SUNA patient with migraine without aura and medication overuse headache responsive to topiramate]

A 34-year-old woman presented with new intermittent short lasing headache around the left eye accompanied with lacrimation. She suffered from anemia and visual disturbance due to thalassaemia beta heterotype and retinitis pigmentosa. She also had continual cephalalgia from about 9 years old, and was taking nonsteroidal anti-inflammatory drug almost every day. After the medical treatment, we diagnosed her headache as migraine without aura, medication overuse headache (MOH) and short lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms (SUNA). Triptan was effective for a migraine headache, but it was ineffective for attacks of SUNA, while topiramate dramatically reduced the SUNA attacks. A headache diary was effective to evaluate the clinical course and the effect of treatment for two different types of headaches by devising the approach to description. A migraine and MOH may coexist with SUNA, and our attention should be paid to the diagnosis and medical treatment in such cases.
