Intrathoracic lymph node tuberculosis is a chronic disease that is not very serious. As long as patients cooperate with doctors throughout the treatment process, it can be easily cured. In intrathoracic lymph node tuberculosis, the primary lesions are prone to absorption and dissipation. When the lesions are small, they do not cause illness and are not visible. However, lymphadenitis is often accompanied by varying degrees of caseous necrosis and heals slowly, manifested as enlarged lymph nodes in the hilar region or mediastinal lymph node enlargement, which is then called intrathoracic lymph node tuberculosis.

Therefore, during the inflammatory stage, it appears as a high - density shadow extending outward from the hilum of the lung, slightly nodular in shape, with blurred edges and poorly defined boundaries with the surrounding lung tissue. The enlarged lymph nodes are hidden in the hilar shadow and are often not clearly visible. If the para - tracheal lymph nodes are involved, the upper mediastinal shadow may show an arc - shaped widening on one or both sides, with a blurred outline.

When nodules are formed, they appear as well - defined, round or oval high - density shadows in the hilar region, more commonly seen in the right hilar area. If several adjacent lymph nodes are enlarged, they may have a lobulated edge.
