![]() ![]() Although it can be used to stage lung cancer they have still not decided if the benefits from the surgery are worth the risks of the procedure, such as not increasing the survival rate and accuracy in staging the cancer. If it is decided to treat these lymph nodes the surgeon can do a mediastinal lymphadenectomy, which was first performed in 1951. If the mediastinal lymph nodes are cancerous what treatment used will depend on the stage and location of the cancer. If a patient has enlarged mediastinal lymph nodes and a biopsy is done under a microscopic examination it can help the physician known what the underlying medical condition is for them being abnormally enlarged. It can also help to determine what treatment would be best used. They may do a biopsy of the lymph node to see if it has been affected by the spread of cancer along with the prognosis. When mediastinal lymph nodes are abnormal they may be access surgically for a variety of reasons such as the suspicion of cancer. This procedure is done under general anesthesia as an outpatient procedure. When this procedure is done a tube will be inserted into your chest to look for the swelling of these lymph nodes and tumors. If you are being evaluated to see if the mediastinal lymph nodes are enlarged secondary to the spread of cancer the radiologist will use a positron emission technology scan (PET) to identify these lymph nodes.īecause mediastinal lymph nodes are not noticeable as they swell they may also do a procedure called a mediastinoscopy to see if these lymph nodes are swollen. To get a more definitive diagnosis they would need to do a CT scan of your chest. When using x-rays taken of your chest they can show a widening of your mediastinal region. They can be evaluated only by using radiographic techniques. Most lymph nodes in your body can be felt through your skin but mediastinal lymph nodes cannot. Lung diseases-these can be caused by a number of pathologic agents that include different types of fungi and bacteria Sarcoidosis – this is an inflammatory disease that affects multiple organs in your body but mostly your lymph glands, skin, eyes, and lungs.Cancer – chronic lymphocytic lymphoma, non-Hodgkin’s lymphoma, testicular cancer and other cancers of your lungs, esophagus, and stomach.These particular lymph nodes can become enlarged due to various conditions that can include: These run in a vertical string along your thoracic cavity near your aorta, trachea, and esophagus. Posterior – these are located posterior, or behind, your heart and anterior, in front of, your spinal column.These lymph nodes surround the major vessels of your heart, thymus, and pericardium, the sac of fibrous tissue that surrounds your heart. Anterior – these are located posterior, or behind, your sternum (breastbone) and anterior, or in front of, your heart.There are two major groups of mediastinal lymph nodes, which are, your: The mediastinal lymph nodes are responsible for helping the thymus gland produce mature lymphocytes, which are a type of white blood cells, and helping to produce bone marrow. These lymph nodes surround your esophagus, pulmonary veins, and the central portion of your lungs, trachea, and aorta. This is the central compartment of your chest cavity between your heart and lungs. Mediastinal lymph nodes are found in the region of your body called the mediastinum. ![]()
