Benign subdural collections of infancy

S Briner, J Bodensteiner

    Pediatrics
    |June 1, 1981
    PubMed
    Summary

    Asymptomatic infants with macrocrania and subdural collections showed normal development without intervention. These collections often resolved or stabilized, indicating a benign course in these cases.

    Area of Science:

    • Pediatric Neurology
    • Neuroimaging
    • Neonatal Medicine

    Background:

    • Macrocrania in infants can be associated with various neurological conditions.
    • Subdural collections require careful evaluation to differentiate from serious pathology.
    • Characteristic imaging findings necessitate understanding their clinical significance.

    Observation:

    • Four infants presented with asymptomatic macrocrania and abnormal transillumination.
    • Computed tomography revealed bilateral subdural collections, normal brain size, modest ventricular enlargement, and prominent sulci/fissures.
    • These imaging findings, typically suggestive of atrophy, were observed in neurologically normal infants.

    Findings:

    • Infants maintained normal development despite significant subdural collections.
    • Head growth was rapid, contrasting with imaging findings suggestive of atrophy.
    • No invasive treatment was required; diagnostic subdural punctures were performed.
    • Subdural collection size remained stable or decreased in all infants during follow-up.

    Implications:

    • The findings challenge the interpretation of prominent sulci and fissures solely as atrophy in infants with macrocrania.
    • This suggests a potentially benign, self-limiting etiology for subdural collections in select asymptomatic infants.
    • Further research is warranted to elucidate the pathophysiology and long-term outcomes of these specific cases.
