 Dural arteriovenous fistula(dAVF)is relatively rare, and its etiology remains uncertain. Generally, dAVF is thought to be acquired and has been reported to develop secondary to sinus thrombosis, head injury, infection, and surgery.

 We report a rare case of dAVF in the anterior cranial fossa that developed remote from the craniotomy site after surgery. A 52-year-old man underwent surgery for hypertensive intracerebral hemorrhage 4 years prior. Perioperative imaging modalities demonstrated no abnormal vascular malformation except for an un-ruptured anterior communicating artery aneurysm. Four years later, follow-up magnetic resonance angiography showed abnormal vascular malformation in the anterior cranial fossa, and cerebral angiography demonstrated dAVF. dAVF and aneurysm were successfully treated. Possible formation of a dAVF should be considered after craniotomy.
