Why Does It Occur (Continued)

Tumours

Tumours can be benign or malignant.  Tumours of the brain cause compression and swelling of surrounding tissues, resulting in poor drainage of CSF.  In the treatment of brain tumours, it is often necessary to control Hydrocephalus, which might only be temporary.

Genetic

In very rare circumstances, Hydrocephalus is due to hereditary factors, which might affect future generations.

Other Causes

There are many other very rare causes of Hydrocephalus.
