Bilateral transverse sinus stenosis predicts IIH without papilledema in patients with migraine

Abstract

Of patients with migraine, 6.7% had bilateral transverse sinus stenosis; 67.8% of these patients had idiopathic intracranial hypertension without papilledema (IIHWOP). These results suggest that patients with migraine who present bilateral transverse sinus stenosis on cerebral MR venography should undergo lumbar puncture to exclude IIHWOP.
