Tracheomalacia is an abnormal collapse of the tracheal walls. It may occur in an isolated lesion or can be found in combination with other lesions that cause compression or damage of the airway. Tracheomalacia is usually benign, with symptoms due to airway obstruction. As such, this condition is often mistaken for chronic asthma or prolonged bronchiolitis The first image is a lateral view of a CXR that shows the trachea during inspiration and expiration. Tracheal collapse of more than 50% during expiration is diagnostic of tracheomalacia. The other image is a 4D volumetric CT of a child with severe tracheomalacia.
