Idiopathic intracranial hypertension

Summary of Idiopathic intracranial hypertension
Idiopathic intracranial hypertension, or pseudotumor cerebri, is a neurological disorder that is characterized by increased intracranial pressure in the absence of a tumor or other etiology seen on imaging. Symptoms include headache, pulsatile tinnitus, and visual symptoms such as diplopia. If untreated, it may lead to swelling of the optic disc that can be seen as papilledema on fundoscopy, which can progress to vision loss. Diagnosis is via elevated opening pressure on lumbar puncture.
