title: [Atypical intrathoracic sarcoidosis: a report of 21 cases].
abstract: OBJECTIVE
  To improve the recognition of atypical intrathoracic sarcoidosis.
  
  
  METHODS
  The clinical data of 21 cases with atypical intrathoracic sarcoidosis were analyzed retrospectively. All the cases had pathological examination data.
  
  
  RESULTS
  The manifestations of atypical intrathoracic sarcoidosis might be as follows: intrapulmonary pathological changes including solitary nodular shadow, atelectasis, unilateral lung consolidation, bilateral lung consolidation and bilateral pulmonary miliary nodes; simple mediastinal lymph node lesion including mediastinal tumor, mediastinal lymph node enlargement plus unilateral pulmonary hilar lymph node enlargement and simple mediastinal lymph node enlargement; pleural lesion including hydropneumothorax and pleural thickening; pulmonary hilar lesion including unilateral pulmonary hilar lymph node enlargement plus mediastinal lymph node enlargement and bilateral pulmonary hilar lymph node enlargement and calcification.
  
  
  CONCLUSIONS
  The clinical manifestations of atypical intrathoracic sarcoidosis are variable. The establishment of the diagnosis cannot be based on image examination alone. With sufficient knowledge of the clinical manifestations of sarcoidosis and other testing methods, the diagnosis can be made correctly.
