We have recently experienced a rare case, idiopathic dural arteriovenous malformation in the anterior cranial fossa, which was operated on and cured completely. The malformation was fed through the anterior ethmoid artery and drained to the cortical vein. Surgery was proceeded with the right frontal craniotomy in extra-and intradural approach. At first, anterior ethmoidal artery was cut at the cribriform plate extradurally. After dura was incised, both the nidus and drainer were coagulated intradurally. The nidus was located at inner surface of the dura. The arachnoid hemorrhage was thought to be caused by rupture of this drainer. He had a quite uneventful postoperative course and was discharged two months after the onset of this episode. Neurological examination after discharge revealed no impairment was found such as his smelling and visual acuity. It was confirmed that the arteriovenous malformation was completely disappeared from a bilateral carotid arteriography taken after the operation.
