Imaging findings
An 18-year-old female presented with a cough. Imaging revealed multiple mass-like opacities containing debris and air-fluid levels. CT demonstrated cystic, branching structures that did not communicate with the proximal bronchi at the hilum, consistent with atretic segments containing trapped secretions and air.
Key takeaways
Bronchial atresia appears as fluid-filled, branching structures that fail to connect with the central airways. These can become infected, leading to air-fluid levels and internal debris mimicking masses or abscesses.
