Quick Reference

(idiopathic intracranial hypertension, pseudotumour cerebri) a syndrome of raised pressure within the skull caused by impaired reabsorption of cerebrospinal fluid. The symptoms include headache, vomiting, double vision, and papilloedema. The diagnosis is made by finding a high opening pressure at lumbar puncture. It normally subsides spontaneously but drug therapy or neurosurgical treatment may be required to protect the patient’s vision.
