fibrosing mediastinitis

(redirected from sclerosing mediastinitis)


inflammation of the mediastinum.
fibrosing mediastinitis (fibrous mediastinitis) mediastinal fibrosis.

me·di·as·ti·nal fi·bro·sis

fibrosis that may obstruct the superior vena cava, pulmonary arteries, veins, or bronchi; most common cause is histoplasmosis; less commonly tuberculosis or unknown.

fibrosing mediastinitis

A disorder most commonly linked to histoplasmosis that is characterised by exuberant fibrosis of the mediastinum, resulting in compromised air and blood flow in mediastinal vessels and pressure on mediastinal structures, with morbidity related to the location and extent of fibrosis.

The spectrum of mass-forming IgG4related sclerosing disease includes fibroinflammatory masses (some of which resemble pulmonary hyalinizing granuloma, see below); inflammatory pseudotumor, plasma cell granuloma type; and sclerosing mediastinitis.

Sclerosing mediastinitis consists of a fibroinflammatory mass within the mediastinum that often secondarily obstructs the trachea and bronchi, esophagus, and veins.
Inoue et al (9) reported a case of sclerosing mediastinitis accompanied by high serum levels of IgG4.
The observations suggest that idiopathic cases of sclerosing mediastinitis may sometimes be a manifestation of IgG4-related sclerosing disease.
Successful treatment of sclerosing mediastinitis with a high serum IgG4 level.
Sclerosing mediastinitis and hyalinizing granuloma share similar histologic features and are both thought to be immunologically derived.
Sclerosing mediastinitis is a rare condition thought to result from many etiologies, an abnormal immunologic response to histoplasmosis being the most prominent one in the United States (Table 2).
Radiologically, sclerosing mediastinitis is divided between 2 types: focal, the most common, and diffuse.
The gross findings for sclerosing mediastinitis are described as tan-yellow, gelatinous masses to gray-white, hard masses that compress or infiltrate mediastinal structures (Figure 6, a).
