Mediastinal lymphadenopathy is an enlargement of mediastinal lymph nodes. These lymph nodes are located in the mediastinum. Mediastinum is located in the chest right in the middle. It is surrounded by the lungs, the breastbone and the backbone and also by the diaphragm muscle. The mediastinum is sometimes referred to as a box, because it contains such vital organs as the heart, blood vessels, and lymph nodes. It also contains the nerves.
There are many causes which can lead to enlargement of lymph nodes in the mediastinum. It can develop as primary condition or appear as a result of other diseases, especially those that affect the lungs. People with obstructive pulmonary diseases are at risk of developing mediastinal lymphadenopathy. Also, having chronic and recurrent bronchitis can also lead to development of mediastinal lymphadenopathy. Some infections and inflammatory diseases, such as sarcoidosis, can also lead to development of mediastinal lymphadenopathy. Sarcoidosis is a collection of inflammatory cells. The most common location of this disease are lungs. In severe cases the mediastinal lymph nodes can become swollen as well. Tuberculosis can also lead to enlargement of these lymph nodes.
In rare cases mediastinal lymphadenopathy can be an indicator of cancer. If swollen lymph nodes are indeed cancerous, it can be the indicator of either lymphoma or lung cancer. Lymphoma is cancer of white blood cells. When it develops, the lymph nodes can become swollen and inflamed. Lung cancer in its progressed form can metastasize to mediastinal lymph nodes if it had not been stopped on time.
