case_images: (A) Initial diagnostic bronchoscopy showing a large endobronchial tumor causing a total obstruction of the right main stem bronchus. (B) Initial CT scan with a large subcarinal mass. (C) First therapeutic bronchoscopy with balloon bronchoplasty. (D) CT scan after the start of systemic treatment and bronchoplasty with a slight permeabilization of the bronchial lumen and a decrease in the size of the subcarinal mass. (E) Second therapeutic bronchoscopy when bronchial electrosurgery and argon plasma coagulation (shown in the picture) were applied. (F) Subsequent follow-up CT scan with a recovery of 50% of the lumen of bronchus intermedius and a decrease in the size of the subcarinal mass. (G) Final bronchoscopic evaluation showing total regression of the endobronchial tumor with a preserved bronchial lumen of bronchus intermedius. (H) Final CT scan with a maintained decrease in size of the subcarinal mass.

case_images: Initial diagnostic bronchoscopy showed complete right main stem bronchus obstruction by an endobronchial tumor (Figure 1(A)). Initial diagnostic CT scan showed a peripheral mass in the right upper lobe with homolateral mediastinal involvement including a large subcarinal mass causing total obstruction of the bronchus intermedius (Figure 1(B)). In the second week of treatment, balloon bronchoplasty by flexible bronchoscopy was applied (Figure 1(C)). Follow-up CT scan showed a decrease in the size of the mediastinal mass and a slight bronchial lumen in the bronchus intermedius (Figure 1(D)). Bronchial electrosurgery with an electrocautery snare achieved partial resection of the endobronchial tumor, and argon plasma coagulation was used for devitalization of the remaining tumor (Figure 1(E)). A CT scan confirmed the recovery of 50% of the lumen of the bronchus intermedius (Figure 1(F)). Bronchoscopy showed total regression of the endobronchial tumor with a preserved bronchial lumen of the bronchus intermedius (Figure 1(G)). In the CT scan, the decrease in size of the subcarinal mass was maintained (Figure 1(H)).
