title: Pulmonary embolism presenting as syncope: a case report.
abstract: BACKGROUND
  Despite the high incidence of pulmonary embolism its diagnosis continues to be difficult, primarily because of the vagaries of symptoms and signs in presentation. Conversely, syncope is a relatively easy clinical symptom to detect, but has varied etiologies that lead to a documented cause in only 58% of syncopal events. Syncope as the presenting symptom of pulmonary embolism has proven to be a difficult clinical correlation to make.
  
  
  METHODS
  We present the case of a 26-year-old Caucasian man with pulmonary embolism induced-syncope and review the pathophysiology and diagnostic considerations.
  
  
  CONCLUSIONS
  Pulmonary embolism should be considered in the differential diagnosis of every syncopal event that presents at an emergency department.
