Idiopathic Intracranial Hypertension Masking as Obstructive Hydrocephalus: A Case Report.

Idiopathic intracranial hypertension (IIH) is a poorly understood phenomenon and its presentation can both mimic and co-exist with other intra-cranial processes. Accurate diagnosis is imperative as ongoing advancements in treatment can yield dramatic positive results. Here we present the case of an individual with signs and symptoms of obstructive hydrocephalus who was ultimately found to have IIH secondary to venous sinus stenosis. After correction of the venous sinus stenosis, resolution in the patient's symptoms was noted. The case highlights some of the unique considerations in approaching patients with IIH and provides a framework for review of current literature related to IIH and venous sinus stenosis.
