Intracranial Hypertension in Unruptured Arteriovenous Malformation: Case Report.

A report of intracranial hypertension in unruptured cerebral arteriovenous malformation (AVMs) is presented. A 16-years-old obese female presented with a first episode of acute severe headache and papilledema. Non-contrasted computer tomography scan demonstrated no evidence of hemorrhage or hydrocephalus. The magnetic resonance imaging brain shows the unruptured AVMs at right temporal area. The AVMs was urgently embolized by glue. Headache completely disappeared within two weeks. The papilledemagradually improved within two weeks and completely recovered within six weeks. Patients with unruptured AVMs should undergo early intervention, either by means of surgical excision or embolization, so as to avoid the permanent deficits of optic nerve such as decreased visual acuity and impaired visual field and optic atrophy.
