Chest radiography and computed tomography images. (A, B, and C) were obtained six, four, and one month(s) before admission, respectively (black arrow indicates interstitial infiltration); (D1) multiple ground-glass opacities on admission; (D2-5) multiple nodular lesions with cavities on both lung fields on admission.

A computed tomography (CT) scan of the chest showed multiple consolidations with cavities in both lung fields (Figure 1). The locations of these infiltrations were consistent with the lung abscesses revealed by the CT on admission; these results indicated that the abscesses had existed for at least six months (Figure 1).

Gram-stain of bronchoalveolar lavage fluid (BAL) showed only capsulated gram-negative rods (Figure 2), and the microorganism was identified as K. pneumoniae by conventional methods.
Multiplex PCR. The isolated strain possessed iutA, rmpA, entB, and mrkD.
