Congenital lobar emphysema with tracheal bronchus
Journal of the Canadian Association of Radiologists
|December 1, 1983
Summary
A rare congenital heart defect, Tetralogy of Fallot, was diagnosed in an infant with respiratory distress. A unique bronchial anomaly was identified, with the emphysematous lobe bronchus arising from the distal trachea.
Area of Science:
- Pediatric Cardiology
- Thoracic Surgery
- Medical Imaging
Background:
- Congenital heart defects and respiratory anomalies can present in infancy.
- Tetralogy of Fallot is a complex cyanotic heart disease.
- Right aortic arch is a rare aortic anomaly.
Observation:
- A three-month-old infant presented with a heart murmur and respiratory distress.
- The infant was diagnosed with Tetralogy of Fallot and a right aortic arch.
- A hyperaerated right upper lobe of the lung was noted on imaging.
Findings:
- Bronchoscopy and bronchography revealed an anomalous origin of the right upper lobe bronchus.
- The bronchus supplying the emphysematous lobe originated from the distal trachea.
- This specific combination of findings appears to be previously unreported.
Implications:
- This case highlights the importance of thorough diagnostic evaluation in infants with complex congenital anomalies.
- Understanding rare anatomical variations is crucial for surgical planning and patient management.
- Further investigation into the embryological basis of such combined anomalies may be warranted.
