title: [Balò's concentric sclerosis in a North-African patient].
abstract: BACKGROUND
  Balo's concentric sclerosis is a rare variant of multiple sclerosis described by Balo in 1928. It is characterized by alternating rings of demyelination and spared myelin.
  
  
  METHODS
  We report a case of Balo's concentric sclerosis diagnosed by the typical MRI findings of concentric rings of demyelination. Medullar and brain localisation were found and clinical course was good under intravenous corticosteroids.
  
  
  CONCLUSIONS
  MRI provides the best diagnostic information for Balo's concentric sclerosis, allowing early diagnosis and treatment.
