===== Idiopathic intracranial hypertension =====

Cerebral [[venous sinus stenosis]] has been reported in up to 90% of patients with IIH. 

Repeat studies after normalization of the [[intracranial pressure]] demonstrated normalization of this finding. 

The cerebral sinus narrowing might be a consequence of the increased [[intracranial pressure]]. However, venous sinus narrowing/thrombosis could cause increased intracranial pressure as well. This situation could represent the chicken or egg debate as to which occurs first
