5. Transthoracic percutaneous CT-guided biopsy of the intracavitary lesion
The patient underwent surgical resection of the right lower lobe superior segment cavity and intracavitary mass, which required right pneumonectomy. The patient did well, with resolution of the hemoptysis. Several years later, the patient returned with hemoptysis, and the background lung disease appeared to have worsened. A follow up thoracic CT was performed (Figure 3).

What is the most likely etiology of the background fibrotic lung disease?
