title: Difficult diagnosis of atypical kawasaki disease in an infant younger than six months: a case report.
abstract: BACKGROUND
  Kawasaki disease (KD) is an acute inflammatory vasculitis of unknown origin.
  
  
  METHODS
  We report the case of a 5-month-old child with an atypical form of KD, characterized by undulating symptoms, who developed an aneurysm of the right coronary artery and an ectasia of the left anterior descending coronary artery.
  
  
  CONCLUSIONS
  This case report underlines the difficulties in recognizing incomplete forms of the illness in young infants, who are at higher risk of cardiac complications.
