case_images: Chest computed tomography (CT,  Figure 1A ) revealed the presence of a soft tissue mass in the left hilum of her lung. Bronchoscopy ( Figure 1B ) revealed mucosal swelling at the opening of the left upper lobe, superficial irregular hyperplasia, lumen occlusion, lesions involving the upper and lower interlobar ridges, and lumen stenosis at the opening of the left lower lobe. Figure 1C ) showed that the tumor size was reduced to 21 x 24 mm. From the good result of neoadjuvant immunotherapy, surgery was recommended again. Before the fifth cycle, chest CT ( Figure 1D ) revealed that the tumor size had increased to 31 x 24 mm. Bronchoscopy ( Figure 1E ) revealed that the lumen was blocked by new growth in the lower portion of the left main bronchus, with an irregular layer of cell proliferation.
