Computed tomography (CT) of the thorax (figure 2) revealed increased interstitial reticulonodular density on the posterior segment of the upper lobe of the right lung and conglomerated LAPs in the pretracheal
, prevascular, retrocaval, aortic pulmonary window, carinal, subcarinal, and hilar areas.
It can be found anywhere between the foramen cecum and the normal pretracheal
Suprastomal stenosis due to cartilage damage is the typical complication following PT and it usually occurs due to an obliquely placed pretracheal
tract leading to tangential contact of tubes and dilators against the anterior tracheal wall.
He had enlarged nodes, many of which appeared necrotic, in the superior mediastinum, pretracheal
region, aortopulmonary window, right hilum and subcarinal areas (Figure 1, panel B; online Appendix Table).
FNA of a pretracheal
mass was diagnosed as metastatic poorly differentiated carcinoma (Figure 5).
4R: Includes right paratracheal nodes and pretracheal
nodes extending to the left lateral border of trachea
Transbronchial needle aspiration of a right pretracheal
lymph node showed numerous lymphocytes, a reactive process, and no tumor cells on cytological examination.
Under slight pressure the dilator was turned clockwise until the first threads were advanced into the pretracheal
In addition, because the pretracheal
, parapharyngeal, and retropharyngeal spaces are in communication with each other, a hematoma or an infection in one of these spaces can easily spread to the others.
A computed tomography (CT) scan of the chest and abdomen revealed pretracheal
lymph node enlargement with diffuse reticulonodular infiltrates, as well as multiple hypodense lesions in the spleen.
Because of a suspicion of lymphoma, computed tomographic scans of the chest and abdomen were performed, which showed moderate bilateral hilar, pretracheal
, and subcarinal adenopathy (Figure, A).
An elliptical incision of the entire defect was carried out down to the pretracheal
