A lymph node is part of the lymphatic system and functions to trap bacterial and cancer cells. The mediastinum is a bag-like area located in the thorax. The terms mediastinal lymph node enlargement and mediastinal lymphadenopathy are not the same. However, when an infection or a disease like cancer is present, the lymph nodes produce additional white blood cells, causing them to swell.

Each of these cancers starts in a different type of cell. Differentiation between sarcoidosis and Hodgkin's lymphoma based on mediastinal lymph node involvement pattern: Evaluation using spiral CT scan. But most lung nodules aren't cancerous. CT is widely used in the evaluation of diseases of the lung and mediastinum. 4.7 ). Share with Email, opens mail client Internal mammary nodes are located in a retrosternal location near the internal mammary artery and veins ( Fig. When the number of biopsies was increased to ten, the yield increased to >90% in all stages of disease. In the absence of a known disease, an enlarged node must be regarded as likely hyperplastic or reactive.
