Clear identification of intrinsic and extrinsic factors causing the acute phase of suppurative meningoencephalitis, as well as its epidemiological and pathogenic characteristics, clinical manifestations and classifications, imaging features and laboratory tests explanations, may contribute greatly to the diagnostic correctness and treatment efficacy, thus promoting diagnostics and medical treatment of this disease which remains ultimately critical to patients′ prognosis.
