title: Cerebral arteriovenous malformation: papilledema as a presenting sign.
abstract: Papilledema as a presenting sign of arteriovenous malformation without evidence of a space-occupying lesion or hydrocephalus is an unusual finding. The pathogenetic theory that seems to explain such cases is the increase of cerebral blood volume leading to intracranial hypertension, thus resulting in papilledema. We present the case of a 31-year-old woman complaining of headaches, with papilledema as the only objective finding. Computed tomography scan and right carotid angiography demonstrated a right mid rolandic arteriovenous malformation. The lesion was totally removed under intraoperative angiographic control.
