190 – Bronchial Stenosis

The light from the left source bronchus is greatly reduced due to a stricture established after a complete bronchial rupture due to chest trauma.

The reduction of the bronchial diameter is concentric and progressive or “infundibuliform”.

The edema thickens the mucosa and the cartilaginous reliefs and also the linear folds of the posterior wall of the bronchus are lost.

191 - Benign bronchial stenosis

X-ray of the previous case: “opaque hemithorax”.

The entire left field is completely opaque, homogeneously and from base to vertex.

The “sign of the naked spine” and a posteroinferior pneumonocele are present due to retraction, as well as the rise of the gastric chamber, indicating pulmonary atelectasis.
