Presentation
Bilateral papilloedema.
Patient Data
prominent subarachnoid space around the optic nerves
mild vertical tortuosity of the optic nerves
flattening of the posterior sclera (papilloedema)
partially empty sella turcica
stenosis of the lateral segments of the transverse sinuses
no evidence of tonsillar ectopia
Annotated images :
prominent subarachnoid space around the optic nerves (yellow)
mild vertical tortuosity of the optic nerves (red arrows)
flattening of the posterior sclera (blue dotted lines)
partially empty sella turcica (red circle)
stenosis of the lateral segments of the transverse sinuses (green arrows)
Case Discussion
MRI findings are reflective of idiopathic intracranial hypertension (a.k.a pseudotumour cerebri).
Bilateral venous sinus stenosis is thought to be the most sensitive/specific finding.
