title: [Bilateral third cranial nerve palsy triggered by an acute relapse of multiple sclerosis].
abstract: BACKGROUND
  We report a case of bilateral third cranial nerve palsy in a patient with a secondary progressive multiple sclerosis.
  
  
  METHODS
  MRI revealed a large hyperintense lesion in T2-weighted images in the mesencephalic area. The clinical and radiological outcome was good after intravenous methylprednisolone. The oculomotor signs were probably caused by this mesencephalic lesion.
  
  
  CONCLUSIONS
  This case of bilateral third cranial nerve palsy is, to our knowledge, the first one occurring in a patient with multiple sclerosis.
