Overview
MRI
MRI findings of parenchyma and ventricles are mostly normal but some anomalies have been reported in IIH patients:
- Posterior sclera flattening (43 to 80 percent)
- Perioptic subarachnoid space distesion (45 to 67 percent)
- Gadolinium enhancement of the prelaminar optic nerve (7 to 50 percent)
- Empty sella (25 to 80 percent)
- Prelaminar optic nerve protrusion (3 to 30 percent)
- Orbital optic nerve vertical tortuosity (40 percent)(54 ta 60)
some of the less common findings are:
- tonsillar ectopia
- Meckel’s cave and cavernous sinuses stenosis
- meningoceles
- Foramen ovale widening(64 ta 67)
