INTRODUCTION AND TERMINOLOGY — The production, absorption, and flow of cerebrospinal fluid (CSF) play key roles in the dynamics of intracranial pressure. Alterations in CSF pressure can lead to neurologic symptoms, the most common being headache. Most often, the headaches associated with low CSF pressure are orthostatic and occur after lumbar puncture, but similar headaches occur with spontaneous low CSF pressure due to spinal CSF leaks and with CSF shunt overdrainage. In addition, trauma, surgery, and other medical conditions have also been associated with low CSF pressure headache [1]. Spontaneous low CSF pressure headache is being recognized with increasing freque
