Correct!
2. Bronchoscopy with transbronchial biopsy
None of the choices other than following the thoracic CT are wrong. However, in my view the best choice in this situation is bronchoscopy with transbronchial biopsy. Although it has lower yield than needle biopsy or VATS, it has a lower complication rate and has the added advantage of visualizing the airways (2). Bronchoscopy with transbronchial biopsies was performed (Figure 3).

What is the likely diagnosis?
