When One Tap Isn't Enough: A Case of Pseudotumor Cerebri Requiring Venous Sinus Stenting.

Pseudotumor cerebri (PTC), or idiopathic intracranial hypertension (IIH), is characterized by elevated intracranial pressure. While most cases are idiopathic, secondary causes, such as cerebral venous sinus stenosis (CVSS), must be thoroughly evaluated, as they require targeted management. Clinical manifestations commonly include headache, pulsatile tinnitus, and transient visual disturbances. If left untreated, severe cases may lead to permanent vision loss due to sustained optic nerve compression. In this report, we present a case of PTC secondary to venous sinus stenosis and review the current approaches to diagnosis and treatment.
