I recently went to the doctor and was told I had a upper respiratory infection. They took chest x-rays and the results came back fine but there were calcified granulomata found in the rigt lower lobe. What does this mean and should I be concerned.
Lung infections sometimes resolve leaving a rounded area in the lung that is largely composed of scar tissue. These old lung nodules often acquire calcium deposits over time. If the calcium deposits are fairly uniform throughout the nodule this is a sign that the calcium is a part of the nodule confirming the benign nature of the nodule. This finding allows the radiologist to make the call that this is a calcified granuloma (that is a lung nodule that has uniform calcium deposits).
