Idiopathic intracranial hypertension

Case contributed by Dr Ammar Haouimi

Presentation

Bilateral papilledema grade 3

Patient Data

Age: 20 years
Gender: Female

The MRI sequences demonstrate:

  • flattening of the posterior sclera bilaterally
  • protrusions of the optic nerve heads 
  • vertical tortuosity of the optic nerves
  • enhancement of the prelaminar (intra-ocular) optic nerves well-visualized on postcontrast axial T1 fat saturation
  • slight enlargement of the subarachnoid space around the optic nerves
  • Partially empty sella turcica (pituitary gland's height=4.5 mm)
  • the cerebral venous sinuses are patent on postcontrast sequences with no significant stenosis (MRV was not performed)
  • no mass lesion is seen at the infra- or supratentorial level.

Case Discussion

MRI findings suggestive of an idiopathic intracranial hypertension

In the absence of a cause for intracranial hypertension, the imaging features should suggest an idiopathic origin
