Pseudotumor Cerebri

What is idiopathic intracranial hypertension (IIH)?

A Answers (1)

  • Idiopathic intracranial hypertension is the name given to a condition characterized by severe headaches and swelling of the optic nerve caused by increased pressure in the fluid surrounding the brain. It is sometimes called pseudotumor cerebri (PTC) syndrome.

    Frequently, the patient will initially be evaluated for a brain tumor because the symptoms of IIH are so closely related to those of a brain tumor. However, it should quickly become apparent from imaging scans like MRI or CT, that a brain tumor is not the issue.

    Patients with IIH or PTC may present with any of the following symptoms:

    • Chronic, severe headaches
    • Ringing in the ears
    • Blurred vision
    • Tunnel vision
    • Loss of vision
    • Double vision
    • Papilledema (swelling of the optic disc)
