In most cases, calcified lymph nodes in the chest are due to old infection with Histoplasmosis. This is a fungus that lives in the soil in the Ohio and Mississippi River valleys. It can cause a cold-like illness or be completely without symptoms. About 80% of people who live in these areas have signs of old Histoplasmosis infection. In almost all people, Histoplasmosis never causes them any problems. Calcified lymph nodes also almost never cause any symptoms. In other areas of the world, old infection with tuberculosis can cause similar changes in the lymph nodes.
