The features are suggestive of congenital pulmonary airway malformation (CPAM) or congenital cystic adenomatoid malformation (CCAM) type I as the cysts are larger than 2 cm in size.

The chest tube may be inserted by the primary clinician suspicious of pneumothorax as the chest radiographic features of CPAM can be similar, or a real pneumothorax that has also occurred (unclear in this case).

Segmental collapse and consolidation in the left lung are probably due to a secondary infectious process.
