Headache attributed to spontaneous low CSF pressure: report of three cases responsive to corticosteroids.

The therapy of headache attributed to spontaneous low CSF pressure (previously defined as spontaneous intracranial hypotension) is still a matter of debate. Epidural blood patch is considered the most effective treatment. However, pharmacological strategies may be considered before blood patch. We report three patients with headache attributed to spontaneous low CSF pressure that were successfully treated with oral prednisone. Additional studies may be useful to prove the effectiveness of corticosteroids in this syndrome.
