The commonest cause of the stenosis was a giant arachnoid granulation. The optic nerve sheaths were larger in MS than controls (p=0.0006). Comparing MS patients with transverse sinus stenosis to those without, the pituitary height was 16% smaller and BMI 25% larger (p=0.02 and 0.003 respectively) Conclusion: In patients with MS, the reduction in venous sinus compliance is associated with venous outflow stenoses in the transverse sinuses which increases the upstream venous pressure and dilates the sagittal sinuses. This finding suggests a continuum exists between MS and idiopathic intracranial hypertension.]]> Thu 24 Mar 2022 11:30:10 AEDT ]]>
