Tracheal bronchus, a rare anomaly, was identified in a VACTERL association case. Dynamic bronchography confirmed this finding, highlighting its utility in diagnosing tracheobronchial anomalies.
Area of Science:
- Pediatric Pulmonology
- Medical Imaging
- Congenital Anomalies
Background:
- VACTERL association is a complex condition involving multiple congenital anomalies.
- Tracheal bronchus (TB) has not been previously reported in association with VACTERL.
- A 5-month-old infant with VACTERL association presented with respiratory distress.
Observation:
- The patient required ventilator support post-patent ductus arteriosus (PDA) repair.
- Chest radiographs revealed persistent right upper lobe hyperinflation.
- Bronchoscopy identified a laterally displaced right main bronchus and left main bronchus stenosis/malacia.
Findings:
- Dynamic bronchography revealed a tracheal bronchus (TB) associated with tracheal stenosis and malacia.
- This case suggests TB may be an additional tracheal anomaly in VACTERL association.
- Bronchoscopy alone may miss ectopic bronchial formations.
Implications:
- Tracheal bronchus may be an underrecognized component of VACTERL association.
- Dynamic bronchography is crucial for diagnosing complex tracheobronchial anomalies.
- Early diagnosis and management of these anomalies can improve patient outcomes.

The Bronchial Tree
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

The Larynx
It is located between the pharynx and the trachea, acts as a passageway for air, and hosts several critical structures, such as the epiglottis, vocal cords, and glottis. The epiglottis acts as a gateway, guiding food to the...
