* Not uncommon in dogs and cats.
* Abnormal drainage of cerebrospinal fluid (CSF) results in dilation of the ventricles of the brain.
** Is a result of either stenosis of:
*** The aqueduct between the 3rd and 4th ventricle, or
*** The foramina further back in the brain stem.
** May also be acquired as a result of compression by tumours or infectious processes.
* Dilation of the ventricles with CSF causes pressure atrophy of the overlying brain tissue.
* Hydrocephalus can be seen at birth.
** Characterised by a dome shaped skull and open fontanelles.
* Hydrocephalus may also be hidden and detected later in life.
