ABSTRACT
Hydrocephalus is the abnormal accumulation of cerebrospinal fluid (CSF) within the ventricles and subarachnoid spaces. It is often associated with dilatation of the ventricular system and increased intracranial pressure (ICP). The incidence of pediatric hydrocephalus as an isolated congenital disorder is approximately 1=1000 live births. Pediatric hydrocephalus is often associated with numerous other conditions, such as spina bifida, tumors, and infections. Hydrocephalus is almost always a result of an interruption of CSF flow and is rarely because of increased CSF production.
