Epidural venous dilatation is commonly seen in patients with spontaneous intracranial hypotension, and its presence often indicates a distinctly altered cerebrospinal hemodynamic/CSF dynamic. With the MR-ICP technique, significant statistical differences were found in various hemodynamic and CSF dynamic parameters. The result suggests that EVD is a representative feature of hemodynamic/CSF-dynamic change in SIH, and also highlights the potential of MR-ICP as a reliable method of assessment for SIH.
