title: Paget's disease of bone presented as normal pressure hydrocephalus: A case report and review of literature.
abstract: BACKGROUND
  Paget's disease is a focal bone disorder manifested as bone overgrowth and disrupted bone integrity as a result of accelerated bone remodelling rate. Rarely, Paget's disease of the base of the skull results in hydrocephalic dementia, and the triad of normal pressure hydrocephalus syndrome is a much more scarce entity.
  
  
  METHODS
  Herein, we report an elderly woman who presented in Imam Khomeini Hospital, Tehran, Iran, with normal pressure hydrocephalus syndrome due to Paget's bone disease. Furthermore, we have reviewed relevant previous studies.
  
  
  CONCLUSIONS
  Paget's disease can be presented as normal pressure hydrocephalus syndrome.
