Atelencephalic microcephaly.
A two-month-old child born with marked microcephaly (head circumference 17cm) was found at autopsy to have gliomesodermal tissue replacing the telencephalon (atelencephaly). This finding, together with genital anomalies and hypoplasia of the extremities, suggests arrest at the fifth week of fetal life. The clinical and pathological features are described and the pathogenesis is discussed.
