Hydrocephalus in children

Hydrocephalus is the accumulation of excessive cerebrospinal fluid in the ventricles and subarachnoid space. If a large amount of cerebrospinal fluid accumulates in the subarachnoid space on the surface of the cerebral hemisphere, it is called subdural hydrocystoma or subdural effusion. Excessive fluid accumulation in the ventricular system is called intraventricular hydrocephalus. Hydrocephalus in children is more common in newborns and infants, often accompanied by enlarged ventricular system, increased intracranial pressure and increased head circumference.
