The genus Naegleria consists of free-living amoebae widely distributed worldwide in soil and freshwater habitats. Primary amoebic meningoencephalitis (PAM) is an uncommon and most likely fatal disease. The incubation period is approximately 7 days. The first symptoms are headache, nasal congestion, fever, vomiting, stiff neck within 3-4 days after the first symptoms, confusion, abnormal behavior, seizures, loss of balance and body control, coma, and death. We describe the case of a child who presented with PAM due to Naegleria sp., fully recovered from the infection without apparent sequels after treatment with a regimen that included miltefosine and voriconazole.

Keywords: Central nervous system protozoal infections; Child; Miltefosine; Naegleria; Voriconazole.
