Hydrocephalus occurs when there is an imbalance between the amount of CSF that is produced and the rate at which it is absorbed. As the CSF builds up, which causes the ventricles to enlarge and the pressure inside the head to increase which in turn causes hydrocephalus.

Hydrocephalus also can occur when there is no known injury or illness to cause it. Hydrocephalus can be classified according to its cause: Obstructive (non-communicating) hydrocephalus is caused by a blockage in the system of cavities (ventricles) in the brain.

The build-up is often Hydrocephalus ex-vacuo occurs when a stroke or injury damages the brain and brain matter actually shrinks. The brain may shrink in older patients or those with Alzheimer's disease, and CSF volume increases to fill the extra space. In these instances, the ventricles are enlarged, but the pressure usually is normal. choroid plexus papillomas (part of the associated hydrocephalus is thought to be due to overproduction of CSF 1.

These causes of hydrocephalus typically lead to increased size in the lateral ventricles, but not an increase in the head size. This is because the cerebral spinal fluid is filling in space from damage caused to the brain from the infection or injury.

Hydrocephalus ex-vacuo occurs when stroke or traumatic injury cause damage to the brain.

This is a potential cause of hydrocephalus in those portions of the ventricular system proximal to the obstruction. Any tumor along the CSF path may be involved.

Prematurity. Other causes include meningitis, brain tumors, traumatic brain injury, intraventricular hemorrhage, and subarachnoid hemorrhage. The four What causes normal pressure hydrocephalus? The cause of excess fluid in the ventricles of the brain may be due to injury, bleeding, infection, brain tumor, CSF surrounds the brain and spinal cord. When the circulatory path of the CSF is blocked, fluid begins to accumulate, causing the ventricles to enlarge and the The most common causes of pediatric hydrocephalus in children in the United States are brain bleeds as a result of prematurity, spina bifida, brain tumors, Hydrocephalus is the abnormal enlargement of the brain cavities (ventricles) caused by a build-up of Hydrocephalus that develops in children and adults · bleeding inside the brain – for example, if blood leaks over the surface of the brain (subarachnoid Hydrocephalus may be present at birth, and can occur with other abnormalities, genetic conditions, or infections.
