Primary mediastinal infection

Primary mediastinal infection is a clinically inexact diagnosis. A small number of cases have been converted from acute mediastinal infection after treatment. The primary mediastinal infection is caused by fungi, histoplasmosis, sarcoplasmosis, tuberculosis and other causes. Mediastinal lymph tuberculosis was once thought to be a specific cause, and lymphadenopathy appeared clinically. After the acute inflammation subsided, the lymph nodes fibrosis and contracted to a chronic infection state. The so-called primary mediastinal fibrous tissue infection often refers to the process of nonspecific, diffuse dense connective tissue fibrosis of unknown cause, also known as idiopathic fibrosing mediastinitis. It can invade the entire mediastinum or a part of the mediastinum. Tracheal stenosis caused by mediastinal fibrous tissue is one of the evidences of lymphatic infection.
