Figure 2. A substantial air-fluid cavity is evident in the right hemithorax, strongly suggestive of an empyema (bottom arrow) causing the collapse of the right lung (middle arrow).

The lower lobe shows breakdown, raising the possibility of communication with the empyema and suggesting the potential presence of a bronchopleural fistula. However, definitive confirmation cannot be ruled out at this stage. These findings suggest the likelihood of chronic infection.
