Abstract

A 69-year-old woman with a previous history of migraine without aura developed throbbing headache in the right frontal region accompanied by nausea, lasting more than 4 hours a day. The headache intensity was more severe than that of usual her migraine headaches. Administration of eletriptan in the previous hospital improved her headaches. However, one month later the patient experienced more intense headaches in the same region and then was referred to our hospital. MR angiography showed abnormal signal intensities in the cavernous sinus. Cerebral angiography revealed blood reflux to the cavernous sinus, leading to diagnosis of cavernous sinus dural arteriovenous fistula. Transvenous embolization of cavernous sinus dural arteriovenous fistula was performed, which resulted in resolution of the patient’s headache. We should be aware that patients with cavernous sinus dural arteriovenous fistula can manifest migraine-like headaches without being accompanied by cranial nerve palsies.
