Figure 1.

A: CT-scan image of Case 1 showed air-space consolidation with peripheral nodular opacities in the left lung with bilateral pleural effusion. B: 47 days after discharge, radiological re-examination exhibited bilateral military nodules in both side of the lung, with prominent spread of the previous consolidation lesion. C: Intra-alveolus lesions filling with eosinophilic “fibrin balls” and loose connective tissues were observed microscopically in the first PNLB (HE, original magnification *200). D: The second PNLB examination revealed typical caseous necrosis (HE, original magnification *200) and areas with positive acid fast bacilli (red arrows in the upper right square pointing at acid fast bacilli, Ziehl-Neelsen staining, oil immersion lens, original magnification *1000).
