title: [The clinical study of pulmonary emphysema with pulmonary fibrosis].
abstract: OBJECTIVE
  Emphysema and interstitial pulmonary fibrosis are two different diseases in clinical manifestation and pathology, but it was noticed that there were cases diagnosed as pulmonary emphysema and pulmonary fibrosis. It is necessary to study the relationship between the clinical aspects of these cases.
  
  
  METHODS
  11 patients with emphysema and pulmonary fibrosis were found in the past five years. Clinical symptoms, radiographic features, arterial blood-gas, lung function testing and computed tomography of the chest were analyzed.
  
  
  RESULTS
  These patients had a long history of cigarette-smoking. Their clinical features are those of both emphysema and pulmonary fibrosis.
  
  
  CONCLUSIONS
  Although emphysema and interstitial pulmonary fibrosis are two different diseases, they could coexist in some patients. Their clinical features do not like either of the two diseases. HRCT is an important method for discovering the coexistance of pulmonary emphysema and interstitial fibrosis.
