Idiopathic Intracranial Hypertension

(Benign Intracranial Hypertension; Pseudotumor Cerebri)

By Stephen D. Silberstein, MD

Idiopathic intracranial hypertension causes increased intracranial pressure without a mass lesion or hydrocephalus, probably by obstructing venous drainage; CSF composition is normal.

Idiopathic intracranial hypertension typically occurs in women of childbearing age. Incidence is 1/100,000 in normal-weight women but 20/100,000 in obese women. Intracranial pressure is elevated (> 250 mm H2O); the cause is unknown but probably involves obstruction of cerebral venous outflow.
