Summary

Schizencephaly, a rare congenital brain malformation, presents with variable clinical and neurodevelopmental outcomes. Early neuroimaging aids in predicting outcomes for affected children.

Area of Science:

  • Neurology
  • Developmental Biology
  • Pediatric Neurology

Background:

  • Schizencephaly is an uncommon congenital brain malformation characterized by cerebrospinal fluid-filled clefts in the cerebral hemispheres.
  • Understanding the diverse clinical, neuroradiologic, and electroencephalographic (EEG) features is crucial for patient management.

Purpose of the Study:

  • To evaluate the clinical, neuroradiologic, EEG, and nosological features of schizencephaly.
  • To assess the neurodevelopmental outcomes in relation to malformation type, epilepsy, and associated central nervous system (CNS) anomalies.

Main Methods:

  • Retrospective review of 13 patients diagnosed with schizencephaly.
  • Analysis of clinical data, neuroimaging (MRI), EEG findings, and neurodevelopmental assessments.

  • Correlation of clinical presentation and outcomes with specific schizencephaly subtypes (unilateral/bilateral, open-lip/closed-lip) and co-occurring CNS malformations.

    • Main Results:

    • The study included 13 patients: 8 unilateral, 5 bilateral; 11 open-lip type. One patient had cytomegalovirus (CMV) infection.
    • Seizures occurred in 9 patients, with outcomes not solely dependent on malformation severity.
    • Neurodevelopmental outcomes were variable, influenced by the extent of schizencephaly and seizure control; bilateral forms with intractable seizures had the poorest outcomes.
    • Eleven patients had additional CNS anomalies, including focal cortical dysplasia in six.

    Conclusions:

    • Children with schizencephaly typically exhibit variable neurological impairment.
    • Earlier diagnosis of schizencephaly and associated CNS malformations through neuroimaging is vital for predicting neurodevelopmental trajectories.
    • The interplay between malformation extent, epilepsy, and co-existing anomalies significantly impacts patient prognosis.
