    Summary

    Computerized transverse axial tomography identified structural brain lesions in 6 of 7 infants with abnormal neurological signs. These findings highlight the utility of this imaging technique in early neonatal neurological assessment.

    Area of Science:

    • Neonatal neurology
    • Pediatric neuroimaging
    • Diagnostic radiology

    Background:

    • Early identification of neurological abnormalities in newborns is crucial for timely intervention.
    • Computerized transverse axial tomography (CTAT) is a valuable tool for evaluating structural brain abnormalities in infants.
    • Abnormal neurological signs in the neonatal period warrant thorough investigation to determine underlying causes.

    Observation:

    • Seven infants, aged 6 days to 8 weeks, presenting with abnormal neurological signs were evaluated.
    • Three of the infants had a history of perinatal asphyxia.
    • General anesthesia was required in only one infant for the CTAT procedure.

    Findings:

    • Structural intracranial lesions were detected in 6 out of the 7 infants studied.
    • The identified lesions included hydranencephaly, cerebral agenesis with dilated lateral ventricles, unilateral cerebral edema, and subarachnoid cysts.
    • Localized cerebral atrophy was also observed in some cases.

    Implications:

    • CTAT effectively visualizes significant structural intracranial pathologies in neonates with neurological deficits.
    • The study underscores the importance of neuroimaging in diagnosing diverse brain abnormalities in the early neonatal period.
    • These findings can guide further management and prognostic assessments for affected infants.
