When a biopsy of the proliferative tissue in the mediastinum reveals only fibrosis, with no evidence of infection, lymphoma or other disorder, then a diagnosis of idiopathic FM may be established. There is no standard therapy mediastlnitis either form of fibrosing mediastinitis. Mediastinal granuloma can also be caused by mycobacteria, so tuberculosis testing should be performed in patients at risk for it.

Such proliferation of mediastinal tissue without calcification is also common for lymphoma, which occurs more commonly than FM, so lymphoma is often the initial provisional diagnosis.

Idiopathic FM seems to be a persistent disease in most patients, even with treatment, but it varies greatly between different patients. In the endemic area, along the Mississippi and Ohio River valleys, nearly all persons are infected in childhood.

Reports of individual patients describe treatment of patients with idiopathic fibrosing mediastinitis with the following drugs: The circulatory system can be affected by direct compression of the pulmonary arteries which carry blood to the lungs or the pulmonary veins which carry blood from the lungs.

Alone we are rare. Symptoms can be present for years before diagnosis. In addition, signs of right heart failure may be prominent. This procedure medjastinitis available by interventional radiologists in most major medical centers.

Pulmonary venous obstruction may lead to pulmonary hypertension. Antifungal therapies are not shown to change fibrosong course for FM, which is more related to ongoing reaction of the immune system, rather than growth of organisms. It could be important for patients to know which structures are occluded in selected circumstances, such as if they needed a central vein catheter for some other problem. HLA are Human Leukocyte Antigens, which are on the surface of nearly every human cell and are important in immune recognition and other functions.

There are to few patients with the Idiopathic form to study whether there is an HLA association. Regular exercise is beneficial for heart and muscle function, and is encouraged for mediaetinitis patients as tolerated.

In my experience, most patients want to know which structures are affected by the disease, perhaps to better understand the cause of their symptoms. Each of the imaging modalities used clinically has unique advantages and disadvantages. Inflammation and fibrosis are related processes that occur together in many different disease processes, and it seems that either one can lead to the other.

Case records of the Massachusetts General Hospital. Because the scar of post Histoplasmosis FM grows very slowly in most patients, treatment would be needed for many years or decades to be effective. There are no studies of FM that followed patients over long periods of time, so the prognosis is not known.
