A member asked:

How common is the need for a shunt with external hydrocephalus?

A doctor has provided 1 answer

Only if necessary: Hydrocephalus is a complex of high brain pressure and extra amount of brain water. Many patients have brain imaging that shows extra brain water but have no pressure. If there is no signs of obstruction along pathways through the brain, it is considered "external" hydrocephalus. If there is no pressure, there is no need for shunt. If there is definite pressure, a shunt is the best treatment.
