Headaches and papilledema secondary to dural arteriovenous malformation

A 21-year-old developed progressive headaches and pulsatile tinnitus. He wa s found to have papilledema and a pulsatile bruit. A dural arteriovenous ma lformation was not recognized on brain CT or MRT, but was well documented o n magnetic resonance angiography and cerebral angiography. Dural malformati ons draining into the superior sagittal sinus can cause increased intracran ial venous pressure and secondarily increase intracranial pressure even wit hout a mass effect.
