Twenty-two children(4 months to 17 years old)with a clincial diagnosis of complex partial seizure(CPS) were examined with a 0.5T MRI scanner using spin-echo sequences. Eleven patients showed abnormal brain MRI findings; two had focal lesions with corresponding seizure foci on the EEG, one arising from temporal lobe(Hippocampal Formation atrophy) and the other from the frontal lobe. Nine patients showed diffuse lesions with inconsistent seizure foci on EEG. The remaining 11 patients were normal on bran MRI; two of them had normal EEG findings and the others either focal or diffuse abnormalities on EEG.
