The case of a 7 month-old baby boy is presented, with a history of several weeks of evolution of personality changes, convulsions and fever. While he was hospitalized, the brain image study showed multifocal cavity lesions, which varied from millimeters to 4 cm of diameter, not producing mass effect. Their biopsy revealed necrotizing encephalitis. In spite of treatment, the lesions progressed and the boy died. The autopsy demonstrated an extensive necrotizing encephalitis with fibrinoid necrotic arteritis, signs of organization, and the presence of parasitic elements with characteristics of trophozoites and cysts of free-living amoebas belonging to the genus Acanthamoeba or Balamuthia. In addition, hypoplasia-dysplasia of the thymus and signs of shock were found. The morphologic elements correspond to the disease described as granulomatous amebic encephalitis and the agent found was identified as Balamuthia mandrillaris (Centers for Diseases Control and Prevention, Atlanta, USA ).

The free-living amebas Naegleria and Acanthamoeba are recognized as causal agents of central nervous system infections. Recently a third free-living ameba, Balamuthia mandrillaris, was identified as the causal agent of granulomatous encephalitis in humans. We report a case of Balamuthia encephalitis in an immunocompetent school-age girl who presented cutaneous lesions that compromised the central portion of the face. The skin biopsy revealed granulomatous lesion with positive PCR for non-tuberculous Mycobacterium. We started treatment for atypical extrapulmonary mycobacteriosis. Nevertheless, the child was readmitted six months later, with progressive neurological involvement, dying about one year after the onset of cutaneous symptoms. The brain necropsy showed the presence of B. mandrillaris cysts and trophozoites. Balamuthia mandrillaris infection should be considered in the differential diagnosis of a patient with chronic granulomatous disease with neurologic symptoms.
