Prosencephalic commissures dysgenesis combined with spinal neural tube defects.
The neuropathological picture of four cases of prosencephalic malformations coexisting with spinal dysraphic anomalies inclined us to discuss the nosological position of these abnormalities. The hypoplastic anomalies of prosencephalic commissures combined with well-cleaved (except for basal ganglia) brain hemispheres allow to think of failure within lamina terminalis. The observations support the opinion that described malformations are consequence of abnormal planning of prosencephalic formation. Our description testifies ones more that as a result of prolonged time of injury a complex picture of developmental anomalies is noted.
