Summary
Schizencephaly, a brain malformation, presents variably even with bilateral lesions. This study highlights diverse clinical and neuroimaging findings in four cases, showing generally good neurodevelopmental outcomes and controlled epilepsy.
Area of Science:
- Neurology
- Developmental Neuroscience
- Neuroimaging
Context:
- Schizencephaly is a rare congenital brain malformation characterized by a cleft in the cerebral hemisphere.
- Understanding its diverse clinical and neuroimaging spectrum is crucial for accurate diagnosis and management.
Purpose:
- To describe the clinical and neuroimaging features of four patients with schizencephaly.
- To illustrate the variability in presentation and outcome, even in cases with bilateral lesions.
Summary:
- Four cases of schizencephaly were analyzed, including variations in lesion laterality (unilateral/bilateral) and lip type (open/closed).
- Despite bilateral lesions in most cases, neurodevelopmental outcomes were generally favorable, with mild hemiparesis noted in two patients.
- All patients experienced epilepsy, which was effectively managed with antiepileptic drugs.
Impact:
- This case series underscores the significant variability in schizencephaly's clinical presentation and neurodevelopmental trajectory.
- Findings emphasize that bilateral schizencephaly does not invariably lead to severe impairment, suggesting a complex interplay of factors influencing outcome.
