Atelencephalic microcephaly

C A Garcia, C Duncan

    Developmental Medicine and Child Neurology
    |April 1, 1977
    PubMed
    Summary
    This summary is machine-generated.

    A severe brain malformation called atelencephaly, where gliomesodermal tissue replaces the telencephalon, was observed in an infant with microcephaly. This condition, along with other anomalies, suggests a developmental arrest early in fetal life.

    Area of Science:

    • Developmental biology
    • Neuroscience
    • Pathology

    Background:

    • Congenital brain malformations present significant diagnostic and research challenges.
    • Understanding early developmental arrests is crucial for identifying etiological factors.

    Observation:

    • A two-month-old infant presented with severe microcephaly (head circumference 17cm).
    • Autopsy revealed gliomesodermal tissue replacing the telencephalon, a condition known as atelencephaly.
    • Associated anomalies included genital abnormalities and hypoplasia of the extremities.

    Findings:

    • The pathological findings suggest a critical developmental arrest around the fifth week of fetal life.
    • Atelencephaly represents a severe disruption of telencephalon formation.
    • The combination of neurological and physical anomalies provides a unique case study.

    Implications:

    • This case highlights the spectrum of severe congenital central nervous system malformations.
    • Further research into the pathogenesis of atelencephaly may offer insights into early brain development.
    • Detailed pathological analysis is essential for understanding rare developmental disorders.
