What causes mediastinal fibrosis?

Most cases have been linked to a specific type of fungal infection called histoplasmosis. Other less common causes of fibrosing mediastinitis include radiation therapy , autoimmune disease , tuberculosis, certain medications, Behcet’s disease, and inflammatory diseases such as sarcoidosis.

How is mediastinitis diagnosed?

Diagnosis of Mediastinitis The diagnosis is confirmed by a chest x-ray or CT. When mediastinitis occurs in a person who has had median sternotomy, doctors may insert a needle into the chest through the breastbone and remove fluid for examination under a microscope (aspiration biopsy).

What is FM lung disease?

Fibrosing mediastinitis (FM) is a rare disease characterized by dense invasive fibrotic infiltration of the mediastinum (middle portion of the chest, situated between the lungs) and/or hilar regions (areas between the upper and lower lobes of each lung) of the chest causing narrowing or occlusion of important chest …

What are the symptoms of mediastinitis?

Common symptoms in patients with mediastinitis include the following:

  • History of an upper respiratory tract infection, recent dental infection (common), or thoracic surgery/instrumentation.
  • Fever, chills.
  • Pleuritic, retrosternal chest pain radiating to the neck or interscapular pain.
  • Shortness of breath.
  • Cough.
  • Sore throat.

What is mediastinal fibrosis?

Mediastinal fibrosis, also referred to as chronic or sclerosing mediastinitis, is a rare condition and constitutes a small fraction of all mediastinal diseases. It causes slow progressive and dense fibrosis of the mediastinum. Specific etiology of this condition is unknown.

What is fibrosis Mediastinitis?

Fibrosing mediastinitis is an uncommon benign disorder characterized by proliferation of dense fibrous tissue within the mediastinum (,1). This entity is also known as sclerosing mediastinitis and as mediastinal fibrosis.

What causes mediastinitis?

Mediastinitis usually results from an infection. It may occur suddenly (acute), or it may develop slowly and get worse over time (chronic). It most often occurs in person who recently had an upper endoscopy or chest surgery. A person may have a tear in their esophagus that causes mediastinitis.

Can histoplasmosis cause pulmonary fibrosis?

Chronic cavitary pulmonary histoplasmosis (CCPH) can develop after acute pulmonary histoplasmosis [15] and is marked by low-grade chronic symptoms, persistent cavitation, and development of pulmonary fibrosis and progressive pulmonary insufficiency [16, 17].

Is mediastinitis fatal?

Review of the literature shows that although DNM is quite rare, this variety of mediastinitis is a highly lethal disease. The mortality rate of this disease is between 40% and 50%.

What is a mediastinal?

How to diagnose idiopathic fibrosing mediastinitis in the USA?

The number of persons with idiopathic fibrosing mediastinitis is estimated to be several dozen in the United States. Diagnosing either form of fibrosing mediastinitis is best accomplished by chest CT, a scan that shows the abnormal tissue in the mediastinum (the space between the lungs).

How does fibrosing mediastinitis affect the lungs?

Fibrosing mediastinitis is a condition that affects the area between the lungs (mediastinum) which contains the heart, large blood vessels, windpipe (trachea), esophagus, and lymph nodes. People with fibrosing mediastinitis have varying amounts of scar tissue in the mediastinum which may cause problems for the organs located there. [1]

What is the prognosis for mediastinal fibrosis?

Prognosis depends on the structures involved. Treatment of mediastinal fibrosis may involve surgical resection, which often may be only palliative given the extent of the fibrosis, or the use of stents to restore patency of critical vessels.

What are the different types of mediastinal fibrosis?

Mediastinal fibrosis may be idiopathic, familial, or associated with various disorders, including infections with other fungi, such as Aspergillus or Cryptococcus, and tuberculosis or sarcoidosis. It has also been described following therapy with radiation, ergot derivatives, and beta-blockers.
