|
What is Hydrocephalus?
|
An imbalance between the production of CSF and its accumulation within the intracranial cavity and in infants enlargement of the head. As the excess CSF accumulates in the ventricle system, the ventricles become dilated/enlarged and the brain is compressed against the skull.
|
|
How can hydrocephalus be caused by a myelomeningocele?
|
The hindbrain (cerebellum) tends to slip down the back of skull and into the spinal cord area causing the CSF to not be able to circulate past that area. Result is buildup of CSF in the ventricles.
