What brain imaging findings do you find reliable to help support a diagnosis of idiopathic intracranial hypertension?

In a study by Bidot et al., PMID 26457687, transverse venous sinus stenosis (TVSS) was the most useful sign of IIH because of its high pooled sensitivity (97%) and specificity(93%). Orbital findings, such as optic nerve head protrusion, posterior scleral flattening, optic nerve tortuosity, and diste...

To assess the reliability of MRI findings in idiopathic intracranial hypertension (IIH), one must consider the sensitivity and specificity of each marker, and reports of these percentages vary widely. Bilateral transverse venous sinus stenosis (TVSS) is the most sensitive and specific neuroradiologi...
