In this manner, is mediastinal lymphadenopathy cancer?
Lymphadenopathy mediastinal – An enlargement of the lymph nodes. Pericardial cyst – A benign growth that results from an "out-pouching" of the pericardium (the heart's lining). Thyroid mass mediastinal – Usually a benign growth, such as a goiter. These types of tumors can occasionally be cancerous.
