    Neuroimaging in infantile spasms reveals that severe cortical atrophy and ventricular dilatation on CT correlate with poorer outcomes. MRI further identifies gray-white matter differentiation issues and periventricular changes linked to developmental delay.

    Area of Science:

    • Pediatric Neurology
    • Neuroradiology
    • Neurodevelopmental Disorders

    Background:

    • Infantile spasms are a severe form of epilepsy in infants.
    • Accurate diagnosis and prognostic indicators are crucial for management.
    • Neuroimaging plays a key role in evaluating brain structure in these patients.

    Purpose of the Study:

    • To analyze computed tomography (CT) and magnetic resonance imaging (MRI) findings in infantile spasms.
    • To correlate imaging findings with patient prognosis and developmental outcomes.
    • To determine the comparative utility of CT and MRI in detecting intracranial pathology.

    Main Methods:

    • Retrospective analysis of CT and MRI scans from 13 patients diagnosed with infantile spasms.
    • Evaluation of specific imaging features including cortical atrophy, ventricular dilatation, gray-white matter differentiation, and periventricular hyperintensity.

  • Correlation of imaging findings with clinical prognosis and developmental status.

    • Main Results:

    • CT revealed cortical atrophy in 8 patients and ventricular dilatation in 9 patients.
    • Severe cortical atrophy or ventricular dilatation on CT was associated with poorer prognosis.
    • MRI identified poor gray-white matter differentiation in all patients and periventricular hyperintensity in 9; high-grade periventricular changes correlated with severe developmental delay.

    Conclusions:

    • CT findings like cortical atrophy and ventricular dilatation are indicators of prognosis in infantile spasms.
    • MRI provides more detailed information, revealing poor gray-white matter differentiation and periventricular changes.
    • MRI is more effective than CT in detecting intracranial pathologies relevant to prognosis in infantile spasms.
