Abstract

Idiopathic intracranial hypertension (IIH) is a rare disorder occurring more frequently in obese women of childbearing age, resulting in increased intracranial pressure (ICP) from an unknown cause. Recent advances in epidemiology, imaging, and treatment have provided a better understanding of IIH in recent years, with better identification of visual risk factors and atypical forms of IIH, including fulminant IIH and spontaneous cerebrospinal fluid leaks, and a randomized clinical trial providing the rationale for the use of acetazolamide. In addition, a revised version of the modified Dandy criteria for the diagnosis of IIH was suggested in 2013, with better definition of IIH in adults and children; however, controversy regarding nomenclature has precluded its acceptance among IIH experts. Finally, questions regarding the best surgical strategy, the indications for venous sinus stenting, and the diagnostic role of the radiologic findings commonly seen in IIH have remained unanswered.
