What is the most likely cause of an anterior mediastinal mass?

Question

If an otherwise healthy adult is found to have an anterior mediastinal mass on CT scan, with no infiltration of surrounding organs and no lymphadenopathy, what kind of tumor is this most likely to be?

Answer 1

Well is the lymphatic system is not involved it is not lymph nodes. What is left may be a growth on the thymus gland which is just deep to the sternum, or perhaps a heart mass. Just wait for the path report or any further testing to find the source.
