Dandy-Walker Malformation,This developmental anomaly ususally consists of: 1) hydrocephalus; 2) maldevelopment of the vermis; 3) dilatation of the fourth ventricle; 4) large posterior fossa; and 5) elevation of transverse sinuses, confluence of sinuses, and tentorium (1).

Arnold-Chiari Malformation,important components of this disorder. The ponto-cerebellar dysgenesis is characterized by failure of the pontine flexure to develop and by caudal herniation through the foramen magnum of the inferior cerebellum and other posterior fossa structures (fourth ventricle, medulla oblongata).

Introduction,. They occur in almost one percent of all live births (80–100/10,000 live births) and represent at least ten percent of all systemic malformations. Approximately 75 percent of fetal deaths, 40 percent of infant deaths and.05 percent of deaths in children under one year of age are caused by CNS disor

Dysgenesis of the Corpus Callosum,l neural tissue and constitutes an important mode of cross-talk between the cerebral hemispheres. Its defective development results in a variable degree of neurologic dysfunction that often is difficult to detect clinically without sophisticated neuropsychiatric testing.

Hydrocephalus denotes ventriculomegaly that is or has been under increased pressure; such pressure may be constant or intermittent. The destructive effect of hydrocephalus is best conveyed by the concept o
