Trachea severely affected by a carcinoma that sits on the posterior wall of the intrathoracic and precarinal portion with 50% light reduction.
Tracheal alterations
147 – Tracheal Tumor
This voluminous formation seems to occupy all the light and deprives us of explaining how distal pulmonary ventilation is achieved.
The reason is that before the muscle relaxation caused by general anesthesia, the tracheal diameter was greater and thus allowed air passage through the periphery of this large occupant lesion.
146 – Tracheal Tumor
Tumor of smooth surface and circumscribed aspect occupies the center of the tracheal lumen, reaching the height of its first ring.
145 – Tracheal Edema in “cobbled street”
Irregular edema in “street cobblestones” of the tracheal wall due to neoplastic embolisms in the submucosal lymphatics.
144 – Lateral Tracheal Compression
In this case, a cystic lymphangioma in the neck barely deflects the trachea.
At hour 4 and 5, the imprint of the rings has been lost by the smooth and regular edema of the mucosa.
143 – Osteochondroplastic Tracheopathy
Osteochondroplastic tracheopathy: tracheal aspect very different from its usual anatomical conformation.
Multiple hard nodular excrescences, irregularly distributed over the tracheal cartilages, upholstered by normal mucosa.
Osteoplastic tracheopathy is an infrequent and asymptomatic condition.

142 – Tracheal Pseudomembrane
Photograph of a tracheal pseudomembrane extracted under rigid bronchoscopy, in a patient with obstructive symptoms and a history of recent orotracheal intubation.
141 – Tracheal Compression In “Sabre Pod”
Trachea in “saber scabbard”.
Notable reduction of its transverse diameter, due to the compression exerted by paratracheal adenomegalies of group 2 and 4.
The mucosa is thickened by regular edema.
140 – Tracheal Light Distortion
Severe distortion of the precarinal trachea by compression that elevates the folds and deforms the entrance of the main bronchi.
The carina, although very asymmetric, remains fine.
139 – Submucosal Protrusion
On the compression of the posterior wall protrudes a submucous and smooth protrusion.
Towards the bottom of the image, one can guess the great widening of the tracheal carina.
