We report a case of cavernous sinus dural arteriovenous fistula (dAVF) that developed after the treatment of a transverse-sigmoid sinus dAVF using transvenous embolization (TVE). A 72-year-old woman presented with headache and left-sided tinnitus. Angiography demonstrated the presence of a left transverse-sigmoid sinus dAVF. After TVE, the patient's symptoms completely disappeared. Three years later, she complained of left-sided tinnitus and diplopia, and angiography revealed the presence of a left cavernous sinus dAVF. We performed transvenous coil embolization, and the dAVF disappeared. TVE has been widely recognized as an effective treatment for dAVF. However, dAVF may develop at a different location after TVE in a few cases. A long-term follow-up is therefore recommended.
