Chronic sclerosing (or fibrosing) mediastinitis, while potentially serious, is caused by a long-standing inflammation of the mediastinum, leading to growth of acellular collagen and fibrous tissue within the chest and around the central vessels and airways. It has a different cause, treatment, and prognosis than acute infectious mediastinitis.
Non-malignant causes are increasing in prevalence due to expanding use of intravascular devices (such as permanent central venous catheters and leads for pacemakers and defibrillators), which can result in thrombosis. [2] Other non-malignant causes include benign mediastinal tumors, aortic aneurysm, infections, and fibrosing mediastinitis. [3]
glucocorticoids or immunosuppressants [1] Mediastinal fibrosis is characterized by invasive, calcified fibrosis centered on lymph nodes that block major vessels and airways. In Europe, this disease is exceptionally rare.

In absence of proper treatment and especially in immunocompromised individuals, complications can arise. These include recurrent pneumonia, respiratory failure, fibrosing mediastinitis, superior vena cava syndrome, pulmonary vessel obstruction, and progressive fibrosis of lymph nodes. Fibrosing mediastinitis is a serious complication and can be ...
The mediastinum (from Medieval Latin: mediastinus, lit. 'midway'; [2] pl.: mediastina) is the central compartment of the thoracic cavity.Surrounded by loose connective tissue, it is a region that contains vital organs and structures within the thorax, namely the heart and its vessels, the esophagus, the trachea, the vagus, phrenic and cardiac nerves, the thoracic duct, the thymus and the lymph ...
Recent studies [66] [68] have revealed that between 2.7 and 6.53 million women in the USA have symptoms of IC and up to 12% of women may have early symptoms of IC/BPS. Further study has estimated that the condition is far more prevalent in men than previously thought ranging from 1.8 to 4.2 million men having symptoms of interstitial cystitis.
[8] Others develop neuroproliferation later in life (acquired neuroproliferative vestibulodynia), perhaps as part of an immune response to infection or allergy. [8] A number of causes may be involved, including subclinical human papillomavirus infection, chronic recurrent candidiasis, or chronic recurrent bacterial vaginosis. [4] [5]
