A. Pelvic MRI, coronal view, proton density fat saturation sequence showing hyperintense nodules in subcutaneous cellular tissue. B. STIR sequence showing enhancement of foreign material (biopolymer) with perilesional inflammation and foreign body reaction. C. Chest CT showing inflammatory changes in the mediastinum, occupation by a hypodense material in the left main bronchus extending into the lower lobe, and necrotizing pneumonia. D. Resolution of the obstruction of the left main bronchus, improvement of interstitial changes and consolidation in lung parenchyma with respect to C.

Chest tomography showed consolidation in the lower left lobe, mediastinum with the oesophageal stent, severe partial oesophageal obstruction by a hypodense material in the upper portion, and compressed left main bronchus (Figure 1C). A new chest CT (Figure 1D) Allowed to view improvement in the obstruction of the left main bronchus and changes in the ipsilateral lower lobe lung parenchyma and decreased oesophageal obstruction at this level.

A. Chest CT coronal view showing compromise with severe esophageal stenosis of the stent and occupation of hyperdense material in the mediastinum with involvement of main bronchi and total obstruction of the left main bronchus. B. Endobronchial fiberoptic bronchoscopy view left the main bronchus occluded by an extrinsic occlusion, right main bronchus with protruding hyaline lesion. C, D. 10x and 20x magnification, respectively, hematoxylin and eosin (H&E) staining, transbronchial biopsy, showing bronchial mucosa from the right upper lobe and lung parenchyma and respiratory bronchial epithelium with chronic mononuclear inflammation in the stroma and presence of foreign refractive material; at higher magnification, pulmonary parenchyma with architectural distortion is observed due to the fact of round refractive material. E, F. 4x and 10x magnification, respectively, H&E staining, resection of right main bronchus lesion, granulation tissue with vascular neoformation, presence of acute inflammatory polymorphonuclear infiltrate in moderate quantity, with ulceration of the superficial epithelium. No refractive material is observed. No granulomas or microorganisms are observed.

In addition, a histopathology exam confirmed the presence of foreign material at the bronchial level and granulomatous reaction (Figure 2 C, D, E, F).
