3.9.2 Tuberculosis of intrathoracic lymphatic nodes


A tubercular disease of the lung root lymphatic nodes and mediastinum are named bronchoadenitis. Bronchoadenitis at tuberculosis are unilateral and bilateral. The unilateral bronchoadenitis meets more often. Infiltrative and tumor-like bronchoadenitis are discerned.

Infiltrative bronchoadenitis.
On chest x-ray the shadow of the lung root is extended on the damaged part, the outside contour is dim, the structure is blurred and intensity is increased. Shadows of enlarged lymphatic nodes are clearly come to light on x-ray tomogram.

Tumor-like bronchoadenitis.
The shadow of the root looks same, as an infiltrative form, but its exterior contour is distinct, regular or polycyclic. The shadow of the upper part of mediastinum is expanded at a defeat of para-tracheal and tracheo-bronchial lymphatic nodes. Its contour remains distinct, as a rule. The defeat of bifurcation lymphatic nodes is revealed usually on the chest x-ray or tomograms.

Outcomes of bronchoadenitis.

Full dissolvement.
Is most often outcome, when the process is revealed in good time and after effective treatment.

Scarring condensation of the root.
The tension bars could be revealed in the field of the root on a chest x-ray, their intensity is raised.

Calcinations could be as seeds, lumpy, shell-shaped and solid. Solid calcinations could be revealed as large, intensive, oval shadows.
