Abstract 256: Effective Resolution of Treatment‐Resistant Idiopathic Intracranial Hypertension With Venous Sinus Stenting in a Patient With Atypical BMI Less Than 30

Idiopathic intracranial hypertension (IIH), previously known as pseudotumor cerebri, is characterized by elevated intracranial pressure with no identifiable cause, often presenting with headaches, visual disturbances, and tinnitus. While the exact etiology is unclear, venous sinus stenosis has been implicated in some cases, potentially impairing cerebrospinal fluid absorption. First‐line treatment typically includes acetazolamide to reduce intracranial pressure; however, venous sinus stenting is considered when medical management fails. Notably, treatment‐resistant IIH is rare in patients with a body mass index (BMI) below 30. This case reports a 35‐year‐old female with a BMI of 29.21, whose IIH was resistant to medical therapy but resolved following successful venous sinus stenting.
