Thoracic radiographs showed a generalised pulmonary hyperinflation, associated with a tracheobronchial bifurcation disruption, most suggestive of a central airway obstruction (Figures 1 and 2).

Thoracic radiographs showed a generalised pulmonary hyperinflation, associated with a tracheobronchial bifurcation disruption, most suggestive of a central airway obstruction (Figures 1 and 2).
First bronchoscopy. A broad-based carina mass occluding approximately 90% of the airway lumen

An irregular, multi-lobulated, intraluminal broad-based mass in the region of the carina was identified, which was occluding approximately 90% of the airway lumen (Figure 3).
First bronchoscopy. Carina luminal diameter restored to approximately 95% of normal, after endoscopic aspiration of the mass

After this procedure, the luminal diameter at the carina was restored to approximately 95% of the normal diameter (Figure 4), providing an immediate improvement in respiratory efforts.
Second bronchoscopy. Relapse of right main bronchi obstruction by the tumour

The second bronchoscopy showed a relapse of the tumour at the level of the right main bronchi where it was placed previously (Figure 5).

A second bronchoscopic debulking of this mass was performed as previously described; however, only a partial resection was achieved (approximately 60% of the lumen was restored, leaving 40% of the mass) (Figure 6).
