Although lumbar punctures (LPs) are used for diagnostic evaluation in idiopathic intracranial hypertension (IIH), they can also provide relief from IIH-associated headache. Conversely, low-pressure headache secondary to LP can be debilitating. Low-volume cerebrospinal fluid (CSF) removal to a "high-normal" closing pressure (CP), approximately 18-20 cm H2O, may result in relief of IIH-associated headache with a lowered frequency of post-LP headache.
