title: Neuroimaging yield in isolated Horner syndrome.
abstract: OBJECTIVE
  To review the yield of imaging in isolated cases of Horner syndrome in order to better understand if and when imaging will ultimately be beneficial.
  
  
  RESULTS
  Imaging in Horner syndrome is commonly performed, however, imaging yield in isolated Horner syndrome has not been extensively studied. A few studies have tried to look into the yield of imaging in such cases and derive conclusions from their findings.
  
  
  CONCLUSIONS
  With limited evidence-based data, the general recommendation for evaluation in pediatric cases of isolated Horner syndrome is physical examination, urinary catecholamines and imaging. In adults, it may be possible to hold-off on imaging of isolated Horner syndrome especially if evidence exists establishing chronic duration.
