A variety of congenital and acquired disorders of the trachea and bronchi may be encountered in the pediatric population. Such disorders are often associated with substantial morbidity and may be potentially life-threatening, especially if the diagnosis is delayed. Affected infants and children often present with respiratory symptoms such as stridor, wheezing, and respiratory distress. Because infants and young children have smaller airway caliber and greater airway collapsibility than adults, they tend to become symptomatic at an earlier stage of disease compared with adult patients. After careful physical examination, imaging evaluation plays an important role in the diagnostic assessment of pediatric patients with suspected disorders of the trachea and bronchi.1-4 The goal of this article is to provide an up-to-date and systematic review of currently available imaging studies and techniques, as well as characteristic imaging appearances of various congenital and acquired tracheobronchial anomalies and abnormalities in the pediatric population.
