title: [The finding of incidental intracranial lesions with magnetic resonance imaging].
abstract: BACKGROUND
  Incidental findings on brain MRI are not rare since the development of MRI as a diagnostic and clinical research tool.
  
  
  BACKGROUND
  Prevalence of cerebral incidental finding, based on research volunteers participating in studies, is estimated from 1.7 to 4 percent. The most frequently detected lesions are intracranial tumors (meningioma, arachnoid cysts, neuro-epithelial tumor) and vascular malformations.
  
  
  CONCLUSIONS
  A better knowledge of the spontaneous outcome of incidental findings would allow adequate management of these patients.
  
  
  CONCLUSIONS
  Clinicians should be aware of the outcome of incidental findings, to reassure patients or trigger a work-up if necessary.
