All About Hydrocephalus


aqueductal stenosishydrocephalus

Hydrocephalus is an abnormality of the normal dynamics of the cerebrospinal fluid (CSF). The CSF is a water-like fluid that surrounds the brain and spinal cord. Normally, it is produced, flows throughout the open spaces in and around the central nervous system (the ventricles and subarachnoid space) and is then re-absorbed. However, some conditions can lead to the accumulation of this fluid or other abnormalities in its flow which can damage the brain and lead to significant symptoms.

In general, hydrocephalic conditions are separated into two categories:

  1. Communicating or Non-Obstructive Hydro: In patients who do not have a visible (on imaging studies) obstruction of the flow of cerebrospinal fluid.
  2. Non-Communicating or Obstructive Hydro: In patients who do have a visible obstruction of the flow of cerebrospinal fluid.


Below you will find a list of types of CSF abnormalities with links to more information about each:
