We report an immunocompetent man in late 30s who presented with headache and visual blurring. Brain MRI demonstrated features of raised intracranial pressure with transverse sinus stenosis. Lumbar puncture revealed high opening pressure and IIH was presumed. The patient underwent left transverse\u2013sigmoid sinus stenting with transient improvement, followed by recurrent headache and rapid visual deterioration. Repeat angiography demonstrated new venous narrowing, prompting stent extension.
