title: Intracranial aneurysms: a game of millimeters.
abstract: OBJECTIVE
  In this review we will discuss the historic development of intracranial aneurysms as a pathologic entity and the potential for overdiagnosis.
  
  
  METHODS
  We conducted a literature search to assess the prevalence, rupture rate, and treatment of intracranial aneurysms.
  
  
  RESULTS
  Intracranial aneurysms represent a necessary example of overdiagnosis.
  
  
  CONCLUSIONS
  A change in the nomenclature of small aneurysms is a possible solution to mitigate patient anxiety from a diagnosis of intracranial aneurysm.
