CTICasesRight middle lobe bronchial atresia
▶ Watch on YouTube — age-restricted, cannot embed here
Imaging findings
Focal hypodensity in the right middle lobe with a branching low-attenuation area representing a mucocele. The right middle lobe bronchus is not visualized, confirming atresia. MRI confirmed the mucocele (T2 hyperintense, non-enhancing).
Key takeaways
Bronchial atresia is characterized by the absence of a visible bronchus and the development of a mucocele distal to the atresia, leading to focal hyperinflation or air trapping.
