Findings In Infants Who Died

No.DiagnosisaEEGEEGMRI
1Infarction in mesencephalon and cerebellumNormalNormalAbnormal signal in mesencephalon and upper brain stem and cerebellum; hemispheres normal
2Wooster-Drought syndromeModerately abnormal voltageFew focal epileptiform potentials on left temporal regionNormal
3UnknownModerately abnormal voltageDiscontinuousMicrocephaly, delay in myelination and small cerebellum
4Nemaline myopathyModerately abnormal voltageNot doneSlightly dilated lateral ventricles; small subarachnoid hemorrhage
5UnknownModerately abnormal voltageBurst suppressionSmall cerebellar vermis, delayed myelination of internal capsule and cerebellum; dilated lateral ventricles
6AsphyxiaBurst suppressionLow voltage, seizuresCerebral edema
7AsphyxiaBurst suppressionNot doneAbnormal signal in basal ganglia and thalami
8AsphyxiaBurst suppressionBurst suppressionAbnormal signal in basal ganglia and thalami, mesencephalon, and brainstem
9AsphyxiaBurst suppressionVery low voltageSevere cerebral edema
10Postnatal asphyxiaSuppressionIsoelectricSubarachnoid, right temporal and intraventricular hemorrhage, cerebral edema
11HemochromatosisSeizures with moderately abnormal voltageBurst suppressionCerebral edema, abnormal signal in white matter and basal ganglia; ventricular dilatation
12Postnatal asphyxiaSeizures with moderately abnormal voltageSeizures, low voltageWidespread abnormal signal in cortex, white matter, basal ganglia, and thalami
13AsphyxiaSeizures with moderately abnormal voltageFrequent seizuresWidespread abnormal signal in cortex, white matter, basal ganglia, and thalami
14AsphyxiaSeizures with burst suppressionIsoelectricWidespread abnormal signal in cortex, white matter, basal ganglia, and thalami
15AsphyxiaSeizures with indeterminate background (classified as suppressed amplitude)Burst suppression, seizuresCerebral edema, abnormal signal in white matter
16AsphyxiaSeizures with burst suppression; later frequent seizures with indeterminate backgroundContinuous seizuresNot done, because infant was fitting continuously
17AsphyxiaModerately abnormal voltageFrequent multifocal epileptiform potentialsWidespread abnormal signal in cortex, white matter, basal ganglia, and thalami
