A chest X-ray (A) and CT (B, C) scan at the initial visit revealed broad consolidation with a positive angiogram sign (arrow) throughout the upper-lobe of the left lung. PET/CT showed a high SUVmax of 26.9 on the consolidation of the left lung (D). A subsequent chest X-ray one week after the percutaneous lung biopsy showed the consolidation getting broader and the development of left pleural effusion (E). A chest X-ray taken two years after chemotherapy revealed a significant improvement in the consolidation and pleural effusion (F).

A chest X-ray and CT scan showed a broad consolidation with an angiogram sign throughout the upper-lobe of left lung, however, other imaging findings such as cavity lesions, small nodules, and bronchiectasis were not observed (Fig. 1A-C). PET/CT showed a high SUVmax of 26.9 on the consolidation shadow (Fig. 1D). The consolidation of the left lung enlarged and left pleural effusion developed one week following the lung biopsy (Fig. 1E). The chest image significantly improved after two years of this chemotherapy (Fig. 1F).
Percutaneous lung biopsy specimens showed caseous granulomas without atypical cells on hematoxylin and eosin (H&E) staining. Scale bar = 250 mum.

Thus, a CT-guided percutaneous needle lung biopsy was performed and the biopsy specimens showed caseous granulomas without atypical cells by hematoxylin and eosin (H&E) staining (Fig. 2), but no bacteria by Kinyoun staining.
