title: [Atypical progressive multifocal leukoencephalopathy (PML) in a patient with pulmonary sarcoidosis].
abstract: BACKGROUND
  Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease of central nervous system due to the JC virus. PML generally occurs in immunocompromised hosts and has a fatal outcome.
  
  
  METHODS
  We report a case of an atypical PML in a patient with pulmonary sarcoidosis: MRI showed multifocal and punctate contrast enhancements. The diagnostic was made by brain biopsy.
  
  
  CONCLUSIONS
  The pathophysiology of this association is probably related to the immunodepression induced by sarcoidosis.
