Granulomatous amebic encephalitis usually occurs in people with a weakened immune system Overview of Immunodeficiency Disorders Immunodeficiency disorders involve malfunction of the immune system, resulting in infections that develop and recur more frequently, are more severe, and last longer than usual. 1 However, the imaging features of amebic meningoencephalitis are non-specific and have usually been described A case of Balamuthia encephalitis in an immunocompetent school-age girl who presented cutaneous lesions that compromised the central portion of the face and died about one year after the onset of cutaneous symptoms.
