bronchial atresia

bron·chi·al a·tre·si·a

severe focal narrowing or obliteration of a segmental, subsegmental, or lobar bronchus, usually associated with distal air trapping and bronchial mucoid impaction distal to the obstruction.

bronchial atresia

occlusion or obstruction of a lobar or segmental bronchus, usually in the left upper lobe; the affected lung segment is often hyperinflated because of leakage of air through the alveolar pores.

For the purpose of this review, we will focus on the most commonly encountered lesions in our practice, which include cystic adenomatoid malformation, bronchopulmonary sequestration (BPS), and bronchial atresia (BA).
Bronchial atresia (BA) is characterized by atresia or stenosis of a lobar, segmental or subsegmental bronchus at or near its origin, resulting in a blindending atretic proximal bronchus and a distended, fluid- filled distal airway that contains variable amounts of mucus, also called mucocele.
2) It presents as an echogenic lung mass during the prenatal period, and other differential diagnoses include cystic adenomatoid malformation (CAM), sequestrated lung, and tracheal or bronchial atresia.
