What is mediastinal disease?
Mediastinal disease refers to an unusual group of tumors that form in the area called the mediastinum, which separates the lungs in the middle of the thoracic cavity. About half of mediastinal tumors cause no symptoms and are found on a chest X-ray or scans for another reason. Occasionally, they will cause symptoms of chest pain or shortness of breath.
Some of the possibilities for mediastinal tumors include thymic gland tumors, enlarged thyroid glands sitting beneath the chest’s bony structure and tumors of the lymphatic system (lymphoma). Other possible reasons for tumors in this area are nerve-related tumors and cysts of the pericardium or lung.
