Congenital malformation of brain
1. Meningocele: Partial or total absence of occipital bones results in protrusion of the meninges from the brain.
2. Meningoencephalocoele: Large defects of occipital bone results in protrusion part of the brain and even ventricle.
3. Anencephaly: Failure of the cephalic part of the neural tube to close. The vault of the skull is missen.
4. Hydrocephaly: Abnormal accumulation of cerebrospinal fluids within the ventricles or between the brain and dura matter.
Spinal cord defects (Spina BIFIDA OCCULATA)
The spinal vertebrae especially in the lumbar region showed failure of neural arch closure and result in exposure of the neural tissues .
