title: Severe acute respiratory syndrome (SARS) in a paediatric cluster in Singapore.
abstract: BACKGROUND
  Severe acute respiratory syndrome (SARS) is a major infectious disease pandemic that occurred in early 2003, and one of the diagnostic criteria is the presence of chest radiographic findings.
  
  
  OBJECTIVE
  To describe the radiographic features of SARS in a cluster of affected children.
  
  
  METHODS
  The chest radiographs of four related children ranging in age from 18 months to 9 years diagnosed as having SARS were reviewed for the presence of air-space shadowing, air bronchograms, peribronchial thickening, interstitial disease, pleural effusion, pneumothorax, hilar lymphadenopathy and mediastinal widening.
  
  
  RESULTS
  Ill-defined air-space shadowing was the common finding in all the children. The distribution was unifocal or multifocal. No other findings were seen on the radiographs. None of the children developed radiographic findings consistent with acute respiratory distress syndrome. All four children showed significant resolution of the radiographic findings 4-6 days after the initial radiograph.
  
  
  CONCLUSIONS
  Early recognition of these features is important in implementing isolation and containment measures to prevent the spread of infection. SARS in children appears to manifest as a milder form of the disease as compared to adults.
