case_images: Chest CT performed on November 4, 2021 showing multiple spots and nodules in both lungs, suggesting infectious lesions compared (cf. the CT on October 27, 2021). There was emphysema in both upper lungs, calcified spots in the left coronary artery, and calcified lesions in the prostate.

case_images: fig1-11795484221146370
case_images: Chest CT showed multiple infections of both lungs with bronchiectasis, and progression compared with the previous examination (10/27/2021) (Figure 1).
case_images: Chest CT performed on November 4, 2021 showing that the orifice of the basal segment of the lower lobe of the right lung was narrow.

case_images: fig2-11795484221146370
case_images: As chest CT showed that the lumen of the basal segment of the right lower lobe was narrow (Figure 2), with the consent of the patient, tracheoscopy was performed.
case_images: Chronic active mucosal inflammation, with erosion and squamous metaplasia of bronchial vegetative growth in the basal segment of the right lower lobe.

case_images: fig3-11795484221146370
case_images: Neobiopathology showed chronic active inflammation of mucosa with erosion and squamous metaplasia (Figure 3).
case_images: Chest CT performed on November 30, 2021 showing that the lung lesions had improved markedly compared with November 4.

case_images: The follow-up CT 2 weeks after discharge showed that the infected lesions were significantly absorbed and subsided (Figure 4).
case_images: New organisms in the orifice of the basal subsegment in the right lower lobe, blocking the orifice during bronchoscopy (November 9, 2021)(see blue arrow).. Tracheoscopy performed on December 21, 2021 showed that the new organisms in the orifice of the basal subsegment in the lower lobe of the right lung had disappeared.

case_images: fig5-11795484221146370
case_images: Under endotracheal endoscopy, a new mass was accidentally found to block the bronchial orifice of the basal segment of the right lower lobe (Figure 5a). Reexamination of tracheoscopy showed that the new organisms in the basal segment of the right lower lobe disappeared (Figure 5b).
