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.

Fibrosing mediastinitis (FM), also known as mediastinal fibrosis or sclerosing mediastinitis, is a rare disorder characterized by proliferation of fibrous tissue within the mediastinum.[sup][1] Although FM is a benign disease, it is often progressive and leads to compression and occlusion of mediastinal structures.

(1,3,5) Retroperitoneal fibrosis, sclerosing cholangitis, Riedel thyroiditis, and sclerosing mediastinitis are all associated with orbital pseudotumors, and they provide a basis for a unifying autoimmune or genetic cause.
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.

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.
Fewer than 300 cases have been reported in the literature since it was first described by Jura in 1924.[1,2] It has been reported under many different names; the names most frequently used in the literature, in addition to sclerosing mesenteritis, include mesenteric lipodystrophy, mesenteric panniculitis, and retractile mesenteritis.[3] It has also been described as part of multifocal or systemic fibrosclerosis, a disease spectrum that also includes retroperitoneal fibrosis, sclerosing mediastinitis, Riedel thyroiditis, and orbital pseudotumor.[4]
