What could cause mediastinal lymph node swelling besides sarcoidosis or lymphoma?
Armand… In common, lymph nodes can be swollen due to inflammation, infection, or cancer. It is fine that the biopsy was negative for cancer. The mediastinal lymph nodes could be a sign of a problem such as an inflammation or infection in the thymus, heart, lungs, esophagus or their surrounding tissues. If you already identify that you have pleurisy, then that seems like the most obvious choice. Good luck and I hope you feel better soon.
