title: [Papilledema and intracranial hypertension].
abstract: Isolated bilateral papilloedema require magnetic resonance imaging (MRI), looking for tumor, hydrocephalus, cerebral venous thrombosis. If MRI is normal and doesn't show any risk for tonsillar herniation, lumbar puncture has to be done with cerebrospinal fluid (CSF) pressure evaluation. Intracranial hypertension without any intracranial lesion (mass lesion, arteriovenous shunt, venous thrombosis) is Pseudotumour Cerebri Syndrome. Risk of such Pseudotumour Cerebri is progressive blindness. Treatment cures intracranial hypertension and stops visual defect.
