Lung diseases

Calcified granulomas



I recently had a chest xray and was told that I have a calcified granulomas in my left lung. I was told it could possibly from inhaling something at a young age. I believe it may be from a button that I inhaled up my nose accidentally and was too afraid of the doctor to tell anyone. Is this granuloma hazardous to my health? The doctor said there is nothing to worry about. Should I have it looked at by a specialist?


Calcified granulomas are very common. Here in Central Ohio, they are usually due to scars from previous infection by a yeast found in the soil called histoplasmosis. These granulomas are usually of no consequence and cause no health problems. Very, very rarely, they can erode into an airway where they can cause cough.
