This 22YO female presented with severe bilateral optic nerve edema and enlarged blind spots. She reported recent weight gain following the placement of an IUD.
MRI and MRV scanning were normal. Lumbar puncture opening pressure was extremely elevated at 55cm H2O, establishing the diagnosis of idiopathic intracranial hypertension (pseudotumor cerebri).
She was evaluated by neurosurgery, and a lumboperitoneal shunt was placed, improving the patient’s symptoms and nerve appearance (not shown).
