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.trinfo:eu-repo/semantics/closedAccessagnosiaarticlecase reportchilddifferential diagnosiselectroencephalographyevoked brain stem auditory responsehumanLandau Kleffner syndromemalepathophysiologypure tone audiometrysingle photon emission computer tomographytemporal lobevascularizationAgnosiaAudiometry, Pure-ToneChildDiagnosis, DifferentialElectroencephalographyEvoked Potentials, Auditory, Brain StemHumansLandau-Kleffner SyndromeMaleTemporal LobeTomography, Emission-Computed, Single-PhotonArticle1012528125295742-s2.0-0037267049N/A
