Granulomatous amoebic encephalitis caused by Acanthamoeba is a rare entity mainly affecting
immunocompromised patients. We reported a case of Acanthamoeba encephalitis of a 1-year-old
immunocompetent child and described the CT and MRI findings of the brain, while reviewing the
relevant literatures. The imaging findings of Acanthamoeba meningoencepalitis in immunocompetent
patients are non-specific and pose a diagnostic challenge.
