Idiopathic intracranial hypertension and transverse sinus stenoses

An 18-year-old woman was diagnosed with idiopathic intracranial hypertension (IIH) and bilateral transverse sinus stenoses (TSS), after presenting with papilledema and decreased visual acuity. Lumbar puncture revealed an opening pressure of >60 cm H2O. MRI showed bilateral TSS believed to be associated with the IIH. Initial treatment consisted of symptom relief by a temporary lumbar drain for cerebrospinal fluid (CSF) diversion, while the pros and cons of a more permanent solution by insertion of a ventriculoperitoneal shunt (VPS) or bilateral transverse sinus stent was discussed. A VPS was inserted since the patient had improved with CSF diversion. MRI verified reopening of the venous sinuses after shunt placement, and the patient remains asymptomatic with no signs of relapse after 3 years of follow-up.
