Tc-99m-HMPAO SPECT was performed in three right handed children with LKS. A relative decrease in perfusion was found in the left temporal cortex of all three patients and also in the left frontoparietal cortex of one patient with hyperkinetic behavior. Degree of regional cerebral perfusion impairment did not correlate with the severity of clinical and EEG abnormalities. Asymmetrical temporoparietal perfusion appears characteristic of LKS. SPECT findings in LKS were evaluated as useful in elucidating the pathogenic features of the disorder in the brain.Englishhexamethylpropylene amine oxime technetium tc 99marticlebrain functionbrain scintiscanningcase reportclinical featurediagnostic valueelectroencephalographyhumanLandau Kleffner syndromemalepathological anatomypriority journalschool childsingle photon emission computer tomographyArticle10.1007/BF03164936
