Thirty patients with a typical orthostatic headache were treated by early lumbar epidural blood patch (EBP) without previously performing lumbar puncture or identifying a CSF leak and with or without typical MRI changes. A complete cure was obtained in 77% of patients after one (57%) or two (20%) EBPs. Spontaneous intracranial hypotension with typical orthostatic headache can be diagnosed without lumbar puncture and can be cured by early EBP in a majority of patients.
