• Bronchial atresia
• developmental anomaly
  • focal obliteration of the proximal segment of a bronchus
  • with hyperinflation of the distal lung.
• Clinical
  • usually asymptomatic
  • may cause
    • shortness of breath,
    • cough,.

Pathology

• Anatomically more like a focal stenosis or atresia of
• segmental or subsegmental airway
  • most commonly apico-posterior segment of the left upper lobe
  • distal airways and lung are normally formed
  • distal airways
    • filled with mucus
  • distal lung

CXR

•  focal ovoid or tubular opacity (finger-in-glove)
• radiating from the hilum associated with a
• distal area of hyperlucent lung.
• CT
  atretic bronchial stump
  • plugged with mucus
  • finger-in-glove appearance
  • distal hyperinflation
