Lung granulomas rarely require treatment, according to Mayo Clinic. Granulomas are small irritations of tissue that are usually caused by an infection. They are most commonly found in the lungs, but they can also be found in other areas of the body.
Granulomas in the lungs have no symptoms and are noncancerous, explains Mayo Clinic. They are usually caused by a fungal infection called histoplasmosis. Most people who have pulmonary histoplasmosis don't even know they have it. People who have histoplasmosis have usually been in Ohio or the upper Midwest for a period of time.
Lung granulomas are usually found during a chest x-ray being given to investigate another condition, states Mayo Clinic. They may appear to be cancerous, but granulomas are benign. When they calcify, or become more dense, they are easier to spot on an x-ray. If the granuloma has not calcified, doctors use a computerized tomography, or CT, to examine and identify it. The CT produces images of the granuloma that can reveal the scarring and calcification that indicate it is a granuloma and not a tumor.
Doctors do not need to treat granulomas and do not feel there is any need for continued monitoring with further x-rays, according to Mayo Clinic.
