title: Horner syndrome in glandular fever: a case report.
abstract: OBJECTIVE
  This study aimed to present and discuss the case of a patient with known glandular fever who presented with Horner syndrome.
  
  
  METHODS
  A 35-year-old patient with known glandular fever developed acute unilateral Horner syndrome, a previously undescribed complication of this common illness. Magnetic resonance imaging and magnetic resonance angiography showed that enlarged intra-carotid sheath lymphoid tissue was likely to be the underlying cause of sympathetic nerve disruption. The case is described, the anatomy of the sympathetic chain is discussed and possible alternative pathophysiological mechanisms are reviewed.
  
  
  CONCLUSIONS
  This is the first report in the worldwide literature of Horner syndrome arising as a result of compression from enlarged lymph nodes in glandular fever.
