Focal electroencephalographic abnormalities and computerised tomography findings in children with seizures.
A persistent focal abnormality was observed in 157 (16%) electroencephalograms undertaken in 964 consecutive children with epileptic and non-epileptic seizures seen over one year. CT head scans were performed in 121 (77%) of the 157 children with a focus on the EEG; 26 (21%) showed an abnormality, and 21 (81%) of the abnormalities were localised. There was no difference in the proportion of abnormal scans associated with a delta or slow wave focus compared with a spike or sharp wave focus. An abnormal scan was uncommon after a single seizure. In only two patients (1.7% of all scans) did the findings on CT alter or greatly influence subsequent management.
