Abstract
Intracranial hypotension is a benign disorder characterized by orthostatic headache. It is caused by CSF leakage, therefore its treatment of choice has been epidural blood patch when initial conservative treatments were not effective. We would like to report a 26-year-old patient with recurrent orthostatic intracranial hypotension in spite of the successful epidural blood patch several times. Her headache was caused by myelography 8 month ago. Cisternography showed a CSF leakage at the level of L1 vertebral body. Headache was resolved completely after epidural blood patch and then recurred 3 times several months after blood patch. Now, she is free from headache for 5 months after last blood patch.
