Chest radiograph showed left basilar lung consolidation with tree-in-bud opacities and stenosis of the LMSB (Figure 1(a)). Chest CT scan showed extensive tree-in-bud opacities with confluent consolidation in the left lung base, enlarged hilar and mediastinal lymph nodes, and stenosis of the LMSB (Figure 1(b)).
(a) Left mainstem bronchus with near-occlusion from obstructing granulation tissue. (b) Metallic foreign body appreciated in the distal left mainstem bronchus. (c) Metallic foreign body after removal.

Flexible bronchoscopy revealed near-occlusion and distortion of the mid-LMSB (Figure 2(a)). Mechanical debulking with endoscopic biopsy forceps allowed for passage of the bronchoscope to the distal LMSB where a metallic foreign body was appreciated (Figure 2(b)). Subsequently, the patient underwent rigid bronchoscopy and a 2.7 centimeter metal foreign body was retrieved using rigid bronchoscopy forceps (Figure 2(c)).
