A granuloma is a small area of inflammation in tissue. Granulomas are most often the result of an infection and most frequently occur in the lungs, but can occur in other parts of the body as well. Granulomas are often found incidentally on a chest X-ray done for some other reason. The most common cause of lung granulomas in the United States is past histoplasmosis, a fungal infection that primarily affects the lungs.
