Lumbar puncture is indicated if meningitis, encephalitis, subarachnoid hemorrhage, or high-low pressure syndromes are considered. Cerebrospinal fluid examination and pressure measurements are not indicated unless the history or examination findings are not consistent with juvenile migraine.

Patients in whom elevated intracranial pressure is suggested or those with focal neurologic deficits should undergo a neuroimaging study prior to a lumbar puncture.
