Intracranial Venous Sinus Stenting in Idiopathic Intracranial Hypertension: A Case Report and Review of the Literature

We describe a case of severe headaches, double vision, and progressive vision loss secondary to a ruptured intracranial cyst (IAC) in a 31-year-old woman with no relevant past medical history. The case is peculiar because drainage of the subdural hygroma led to a minimal improvement in vision with persistent elevated intracranial pressure (ICP). Further exploration revealed transverse sinus stenosis necessitating stenting. Evaluation post-stenting showed marked reduction of ICP and improvement in symptoms. This report underscores the importance of comprehensive work-up and suspicion of multiple underlying etiologies that may be crucial to complete resolution of presenting symptoms in some cases. We provide an overview of the clinical indications and evidence for venous sinus stenting in treating idiopathic intracranial hypertension (IIH).

Automated summary

A 31-year-old woman with no past medical history presented with severe headaches, double vision, and progressive vision loss due to a ruptured intracranial cyst. Drainage of subdural hygroma only led to minimal improvement in vision, with persistent elevated intracranial pressure. Further evaluation revealed transverse sinus stenosis necessitating stenting, which resulted in marked reduction of ICP and improved symptoms. This case highlights the importance of comprehensive work-up and consideration of multiple underlying etiologies for complete resolution of symptoms in certain cases.
