Communicating hydrocephalus
Hydrocephalus is the condition where the fluid spaces in the brain (Ventricles) become enlarged. One of the three basic types is known as Communicating Hydrocephalus. This is a condition where the Cerebro-Spinal Fluid (CSF) inside of the ventricles communicates or is open to, the fluid spaces surrounding the brain. This type usually occurs as a result of some sort of dysfunction of the absorption channels known as the Arachnoid Villi.
