A month later, cough with mild dyspnea persisted, and although there was partial resolution of the right lower lobe (RLL) collapse, bronchoscopy showed critical stenosis of the RBI (Figure 1).

(A) Foreign body tightly impacted in right bronchus intermedius (RBI),
(B) post-foreign body extraction RBI stenosis, (C) balloon

Check bronchoscopy done after 3 weeks showed critical RBI narrowing, which was recanalized with balloon bronchoplasty (Figure 2), and stayed patent in follow-up over a period of 3 months.

(A) Cryo-extraction of foreign body impacted in right main bronchus, (B)
narrowed right bronchus intermedius, (C) balloon dilatation of the
stenotic segment, and (D) patent distal right bronchial tree.

A guide wire was passed across the stenosis, and balloon bronchoplasty of the stenotic segment was repeated (Figure 3), restoring patency with no restenosis at 4-month follow-up.
