CTICasesCongenital Pulmonary Airway Malformation with Bronchial Atresia
Imaging findings
CT shows a well-circumscribed, hyperlucent, spherical cystic space in the right upper lobe containing a tubular, densely calcified structure at its center, representing a calcified mucoid impaction (broncholith) in an atretic segmental bronchus.
Key takeaways
Congenital pulmonary airway malformation (CPAM) can coexist with bronchial atresia as a hybrid developmental lesion. While bronchial atresia typically presents with a fluid-filled or mucus-filled bronchocele, long-standing cases can show inspissated, calcified secretions resembling a broncholith.
