Severe visual loss may occur in patients with pseudotumor cerebri (PTC), also known as idiopathic intracranial hypertension. Transverse sinus stenosis is 1 cause of PTC syndrome. Although the role of transverse sinus stenosis in the pathogenesis of the disease remains controversial, recent case series of transverse sinus stenting have reported very high rates of symptom response and resolution of papilledema with improvement or at least stabilization of the visual fields and visual acuity (Ahmed et al., 2011).1 We report a previously unpublished complication of diffuse, nonaneurysmal subarachnoid hemorrhage following angioplasty and stenting in a patient with refractory PTC.
