Patients with idiopathic intracranial hypertension (IIH) frequently present to the neuro-ophthalmologist prior to obtaining any neuroimaging studies. Although magnetic resonance (MR) imaging of the brain with and without contrast is the recommend diagnostic imaging modality for IIH, some authors advocate routine inclusion of MR venography (MRV), both to screen for venous sinus thrombosis as well as transverse sinus stenosis. Two experts debate whether MRV should be routinely include in the diagnostic work up of patients with suspected IIH.
