Successful Treatment of an Adolescent With Naegleria fowleri Primary Amebic Meningoencephalitis

Naegleria fowleri is a thermophilic, free-living ameba that causes primary amebic meningoencephalitis. The infections are nearly always fatal. We present the third well-documented survivor of this infection in North America. The patient’s survival most likely resulted from a variety of factors: early identification and treatment, use of a combination of antimicrobial agents (including miltefosine), and management of elevated intracranial pressure based on the principles of traumatic brain injury.
