Figure 2 Fibreoptic bronchoscopy (March 9, 2009), showing nodes in the right upper lobe opening.

Figure 3 Transfiberoptic bronchoscopy mucosal biopsy, showing polypoid hyperplasia of granulation tissue and hyperplasia of capillary with inflammatory cells (hematoxylin and eosin stain, ×200). A: Tracheobronchial nodules; B: Left lingular lobe.

Figure 4 Computed tomography scan of the thorax (April 5, 2009), showing multiple patchy shadows in both lung fields almost disappeared.

Figure 5 Fibreoptic bronchoscopy (April 6, 2009), showing nodes in the right upper lobe opening diminished obviously.
