title: An Unusual Cause of Chest Pain in a Young Healthy Female.
abstract: BACKGROUND
  Infection of the sternoclavicular joint is an uncommon disease that is usually seen in patients with underlying risk factors such as prior trauma, intravenous drug use, or diabetes mellitus. The true pathophysiology remains unknown, but underlying bacteremia has been found in a number of cases. Without proper diagnosis and treatment, severe complications such as mediastinitis, sepsis, or death can occur.
  
  
  METHODS
  This is a case of spontaneous stenoclavicular septic arthritis in an otherwise healthy female. The patient's lack of risk factors and minimal examination findings highlight the unusual nature of the case, as well as the challenges it presents in making an early diagnosis. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS CONDITION?: Emergency physicians should consider sternoclavicular joint infections in patients who present to the emergency department with chest pain, even in patients without risk factors. They should especially consider the diagnosis in patients with suspected musculoskeletal etiologies or in those with return visits for chest pain. Although most patients do well with treatment, the infection can be life threatening without appropriate interventions.
