PY - 2011 T2 - Rudolph's Pediatrics, 22e AB - Hydrocephalus is a condition in which there is an accumulation of cerebrospinal fluid (CSF) within the ventricles, leading to increased intracranial pressure. Hydrocephalus may be caused by increased production, decreased absorption, or obstruction to flow of CSF. By contrast, ventricular dilatation due to loss of brain tissue or atrophy is not considered to be hydrocephalus.
