title: [Landau-Kleffner syndrome (acquired epileptic aphasia)].
abstract: Landau-Kleffner syndrome is characterized by a complex group of symptoms including deterioration in language skills, seizures, and abnormal electroencephalography findings. A six-year-old male patient had aphasia for three years and generalized tonic-clonic epileptic seizures for two years. Pure-tone audiometry and auditory brain-stem response audiometry findings were normal. He had verbal auditory agnosia rather than true aphasia. Cranial computed tomography and magnetic resonance imaging studies did not show any abnormal findings. Single-photon emission computed tomography showed hypoperfusion in the right hemispheric temporal lobe. Despite treatment with corticosteroids and intravenous immunoglobulins, multiple exacerbations were interspersed in a four-year follow-up period.
