Globoid cell leukodystrophy: cranial computed tomography and evoked potentials.

B T Darras, E S Kwan, H E Gilmore

    Journal of Child Neurology
    |April 1, 1986
    PubMed
    Summary

    Early infantile globoid cell leukodystrophy presents with abnormal brain stem auditory evoked responses (BAERs) and visual evoked potentials (VEPs). Cranial CT scans reveal progressive cerebral atrophy, suggesting this rare leukodystrophy in infants.

    Area of Science:

    • Neuroscience
    • Pediatric Neurology
    • Medical Imaging

    Background:

    • Globoid cell leukodystrophy (GLD), also known as Krabbe disease, is a rare, severe lysosomal storage disorder.
    • It is characterized by the accumulation of galactolipids in the brain's white matter, leading to demyelination.
    • Early diagnosis is crucial for potential therapeutic interventions, though prognosis remains challenging.

    Observation:

    • This case study presents an infant diagnosed with early infantile globoid cell leukodystrophy.
    • Abnormalities were detected in electrophysiological tests, specifically brain stem auditory evoked responses (BAERs) and flash visual evoked potentials (VEPs).
    • Serial cranial computed tomographic (CT) scans demonstrated progressive cerebral atrophy and multiple areas of increased attenuation.

    Findings:

    Related Experiment Videos

    • The combination of abnormal evoked potentials (BAERs and VEPs) and characteristic CT scan findings (progressive atrophy, increased attenuation) is highly suggestive of globoid cell leukodystrophy in infants.
    • These neuroimaging and neurophysiological markers provide critical diagnostic clues.
    • The study highlights the utility of integrating evoked potentials with cranial CT for early detection.

    Implications:

    • Concomitant abnormal evoked potentials and CT findings can serve as early indicators for globoid cell leukodystrophy.
    • This diagnostic pattern aids in timely identification, potentially improving management strategies for affected infants.
    • Further research into the specific electrophysiological and radiological signatures of GLD can refine diagnostic protocols.
