Tracheal Diseases The trachea is confused by way of profuse conditions that subsume infections, neoplasms and changes in calibre kin to associated pathologies in adjacent structures. Tracheal compression and displacement comm- only occurs with adjacent neoplasms originating in the neck or mediastinum or both. Tracheal enlargement occurs in patients with emphysema and constrictive bronchiectasis. When the trachea is compressed in the coronal plane but elongated in the sagittal smooth, a sabre-sheath trachea results. Crystal clear radiographs may make clear opacities in the air-shadow of the trachea, singularly in the lateral view. The employment of reconstruction techniques, outstandingly sagittal and coronal reconstructions and accepted endoscopy concede healthier perception of these pathologies.
