     When a child is born with hydrocephalus there could be many reasons why. It could be a result of the condition spina bifida which is when a child's spine did not develop properly. Second babies can be born with hydrocephalus if they have aqueduct stenosis.

Also children may contract hydrocephalus from the following ; Bleeding in the brain, injury before or after child birth, infections that affect the nervous system, tumors in the brain or spinal cord, and injury or trauma.
