 A 56-year-old man experienced a sudden onset of left hemiparesis. The computed tomography(CT)scan revealed a lobar hemorrhage in the right fronto-parietal lobe. After his admission, deep vein thrombosis was detected in his left lower limb, and angiograms taken on the 36th day of hospitalization revealed cerebral venous sinus thrombosis. Anticoagulant treatment was induced. After 21 months, he experienced a sudden onset of left hemiparesis again. The CT scan revealed a new lobar hemorrhage in the right frontal lobe, and angiograms revealed that two dural arteriovenous fistulas(dAVF)developed in the superior sagittal sinus(SSS)and the left transverse-sigmoid sinus. The one in the SSS had retrograde drainage from the bilateral middle meningeal artery, and we performed transarterial embolization with 50% n-butyl-cyanoacrylate. Postoperative course was uneventful and no further stroke occurred.

 Intracranial dAVF is known to be an acquired disease caused by venous hypertension, but we rarely find new development of dAVFs after venous diseases. This patient's case will help to elucidate the pathophysiology of dAVF.
