An unusual cause of obstructive emphysema

Area of Science:

• Pediatric Cardiology
• Thoracic Surgery
• Pediatric Radiology

Background:

• Foreign body aspiration is a common cause of respiratory distress in infants.
• Enlarged left atrium can cause extrinsic compression of the tracheobronchial tree.
• Anomalous origin of the left coronary artery is a rare congenital heart defect.

Observation:

• A 6-month-old infant presented with symptoms and radiographic findings suggestive of a foreign body in the tracheobronchial tree.
• Physical examination revealed signs consistent with airway obstruction.
• Radiography showed signs that were initially interpreted as a possible foreign body.

Findings:

• Further investigation, including advanced imaging, revealed extrinsic compression of the left main bronchus.
• The compression was caused by a significantly enlarged left atrium.
• The underlying etiology was identified as anomalous origin of the left coronary artery.

Implications:

• This case highlights the importance of considering cardiac causes of respiratory symptoms in infants.
• Accurate diagnosis of extrinsic bronchial compression is crucial for appropriate management.
• Early recognition and treatment of congenital heart defects like anomalous coronary artery origin can prevent life-threatening complications.
