Neuroimaging Features of Idiopathic Intracranial Hypertension Persist After Resolution of Papilledema

Idiopathic intracranial hypertension (IIH) is characterized by elevated intracranial pressure of unknown etiology. Papilledema is a key clinical finding associated with IIH and is used to both diagnose and monitor the course of the disease. Newer criteria allow the diagnosis of IIH without papilledema, provided certain neuroimaging findings are present. These findings have previously been shown to occur in patients with active papilledema. Using a retrospective cross-sectional study, we analyzed the persistence of these features following resolution of papilledema
