Learning objectives

To review and illustrate the computed tomography findings of cigarette smoking-related lung diseases.

Background

Cigarette smoking is a major public health problem, and it is the most common cause of inhalation lung injury. Inhaling the complex mixture of chemical compounds present in tobacco smoke causes several adverse health effects, including injury to the tracheobronchial tree and pulmonary parenchyma. Cigarette smoking-related lung diseases are a wide group of diseases which include chronic obstructive pulmonary disease (COPD), lung cancer and smoking-related interstitial lung diseases (ILDs). COPD is characterized by persistent airflow limitation. It is caused by an enhanced chronic inflammatory responseto...

Imaging findings OR Procedure details

Based on our department database, we will present and illustrate the CT characteristics of smoking-related lung diseases. COPD COPD includes several distinct but overlapping syndromes, including chronic bronchitis, emphysema, reversible and irreversible small airways disease. CT findings of COPD include: 1.Emphysema: 1.1.Centrilobular emphysema(CLE): CLE is characterized by destruction of centrilobular alveolar walls with enlargement of respiratory bronchioles and associated alveoli. It is the most common type of smoking-related emphysema, being usually upper lung predominant; CT imaging findings: small well-defined or poorly defined areas of low...

Conclusion

Cigarette smoking is associated with the development of several lung diseases, some of which may coexist in the same patient. CT has an important role in the evaluation of smoking-related lung diseases.
