In brief: Hydrocephalus or IIH

Hydrocephalus usually refers to a condition in which the cerebrospinal (CSF) fluid that surrounds the brain becomes trapped in the ventricles where much of this fluid is stored and the ventricles become dilated.
There are many known causes. Iih is a condition in which the pressure is increased in the head but the ventricles are not dilated. The cause of iih remains less clear.

In brief: See below

Hydrocephalus, or water on the brain is abnormal enlargement of the internal fluid cavities of the brain (ventricles).
Treatment usually involves placement of a shunt device. Idiopathic intracranial hypertension (ich) or pseudotumor cerebri is abnormally increased cerebral spinal fluid pressure of unknown cause and without hydrocephalus. Treatment can be medical or surgical if med treatment fails.
