Dural arteriovenous malformations may be congenital, but most dural arteriovenous malformations are acquired lesions. The acquired dural arteriovenous malformations are rarely associated with brain tumors. We describe a case of dural arteriovenous malformation at the non-dominant transverse-sigmoid sinus associated with a convexity meningioma on the same side. The lesion was spontaneously disappeared after removal of the meningioma, even though the dural arteriovenous malformation was not manipulated. The authors describe a possible pathophysiology of dural arteriovenous malformations associated with tumors at the remote area and spontaneous closure after tumor resection.
Key Words: Dural arteriovenous malformation; Sinus thrombosis; Meningioma; Pathophysiology
