Primary amoebic meningoencephalitis with Naegleria fowleri: clinical review.

Two children with primary amoebic meningoencephalitis secondary to Naegleria fowleri are reported. Both children died, and the causative agent was identified at autopsy. Presentation and outcome conformed to the usual course of primary amoebic meningoencephalitis and reaffirm the gravity and rapid progression of this infection. The epidemiology, microbiology, diagnostic considerations, and treatment are discussed. Primary amoebic meningoencephalitis should be considered in the differential diagnosis of children with meningitis or encephalitis.
