Results of computed tomography in "neurologically normal" children after initial onset of seizures.
A combined retrospective and prospective study assessed the results of computed tomographic (CT) scans in infants and children without neurologic deficit who presented with initial onset of seizures. Of 101 pediatric patients, 81 had afebrile seizures and 20 had complicated febrile seizures (i.e., focal, multiple, or prolonged). Seven children (7%), 6 with afebrile and 1 with a febrile seizure, had CT abnormalities. Four patients (4%) required further diagnostic workup including angiography and/or surgery. Children with afebrile focal seizures were more likely to have an abnormality than those with afebrile generalized seizures without focal components (13% and 4.9%, respectively). This study demonstrated a lower percentage of overall CT abnormalities, yet a similar percentage of "therapeutically important" abnormalities, in neurologically normal children with new onset of seizures when compared to previous reports of children with chronic seizures. Although an abnormal CT was more likely to be associated with an abnormal electroencephalogram, a normal result did not eliminate the possibility of an abnormal CT.
