AB Hydrocephalus  is  the  progressive  enlargement  of  the  ventricular  system  secondary  to  excessive  cerebrospinal  fluid  (CSF)  volume.  It  is  caused  by  an  imbalance  between  CSF  production,  absorption,  and  impaired  CSF  circulation.  Hydrocephalus  is  associated  with  increased  intracranial  pressure  (ICP)  and  an  enlarging  head.  Typically,  an  occipitofrontal  head  circumference  of  >2  standard  deviations  of  normal  is  consistent  with  macrocephaly  due  to  hydrocephalus.  Hydrocephalus  occurs  when  the  ventricles  are  >15  mm  wide.  Occasionally,  hydrocephalus  can  present  with  normal  head  size  but  with  marked  ventricular  dilatation.
