title: MRI in acute hemiplegia of childhood.
abstract: OBJECTIVE
  Acute hemiplegia in childhood is rare, the underlying etiology frequently obscured and the pathological site unidentified.
  
  
  METHODS
  Magnetic resonance imaging (1.5 T Magnetom) was performed in two cases with hemiplegia followed by repeated studies at 3 and 16 months, respectively, after the initial examinations, including CT and angiography, were negative.
  
  
  RESULTS
  MRI demonstrated otherwise occult lesions in the brain stem and showed the subsequent partial resolution consistent with infarction.
  
  
  CONCLUSIONS
  MRI should be employed in those children with acute hemiplegia in whom no underlying cause is elicited.
