Balamuthia mandrillaris causes granulomatous amoebic encephalitis, which is frequently fatal. There are few reports of survival in children. A 4-year-old child developed severe meningoencephalitis with multiple intracranial ring-enhancing lesions. Empiric therapy was commenced after a biopsy was performed, and the patient had a good clinical response. Molecular testing and indirect immunofluorescence later confirmed the diagnosis of Balamuthia encephalitis. Diagnosis of Balamuthia encephalitis is often delayed. The literature is reviewed with particular reference to reported survival. Prompt tissue diagnosis and initiation of therapy are common features among survivors. In previous reports, miltefosine was not used to treat children, but it was well tolerated in this case and should be considered as a therapeutic option.
