CTICasesPulmonary sling
Imaging findings
Chest CT in an intubated 12-month-old child shows an anomalous origin of the left pulmonary artery from the right pulmonary artery, wrapping posteriorly around the distal trachea/main bronchus (pulmonary sling) and causing severe focal compression and bronchomalacia of the left main bronchus.
Key takeaways
A pulmonary sling is a congenital vascular anomaly where the left pulmonary artery arises from the right pulmonary artery and courses between the trachea and esophagus to reach the left lung. It can cause severe focal tracheobronchomalacia or be associated with complete cartilaginous tracheal rings (ring-sling complex).
