[Pseudotumor cerebri syndrome].

Pseudotumor cerebri is a non-tumor related idiopathic or secondary intracranial hypertension. It is typically associated with papilledema and headache and patients are typically female, young and obese. Diagnosis is established by neuroimaging by magnetic resonance imaging (MRI), cerebral MR venography (MRV) and lumbar puncture. Papilledema is assessed by ophthalmoscopy, ultrasound and optical coherence tomography. Ophthalmologists monitor visual function by measuring visual acuity and visual field testing. Therapy of patients not facing immediate visual loss encompasses weight reduction and administration of carbonic anhydrase inhibitors. In vision-threatening situations invasive procedures are necessary, such as repeated lumbar puncture, liquor drainage, optic nerve sheath fenestration and endovascular venous stenting.
