Summary
Bronchiectasis is defined as the permanent dilatation of bronchi. The Reid classification includes three grades of progressively more severe bronchial injury: cylindrical, varicose, and cystic. Clinically, bronchiectasis is usually classified into either cystic fibrosis (CF)-related bronchiectasis or non-CF-related bronchiectasis. Physiologically, bronchiectasis is characterized by airflow obstruction. Significant complications that occur in bronchiectasis include hemoptysis, recurrent pneumonia, empyema, pneumothorax, and abscesses. Multidetectorrow CT scanning is used in the assessment of obstructive airway disease where bronchiectasis is one component of lung injury that needs to be assessed on every study. Disease entities with a high association with bronchiectasis include CF, non-tuberculous mycobacterial infection, allergic bronchopulmonary aspergillosis (ABPA), alpha-1 antitrypsin deficiency, immunodeficiencies, and primary ciliary dyskinesia.
