Imaging findings
CT of a 32-year-old trauma patient demonstrates extensive, bilateral, multifocal cystic masses involving almost every lobe of the lung. The cysts show no distinct wall/capsule and exert mass effect, splaying and stretching the adjacent normal pulmonary parenchymal and bronchovascular structures.
Key takeaways
While congenital pulmonary airway malformations typically present as a localized, unilateral process in childhood, rare cases can demonstrate extreme multifocal, bilateral involvement spanning multiple lobes that persists into adulthood.
