If a calcified granuloma is causing symptoms, surgery may be necessary to remove it, according to Mayo Clinic. However, calcified granulomas in the lung are benign and usually do not need any treatment. If the granuloma was caused by an infection that is still active, this infection should be treated, says Cancer Connect.
Inflammation in the lung tissue can cause a granuloma to form. This inflammation can be caused by fungal, bacterial or parasitic infections such as histoplasmosis or tuberculosis, reports Mount Sinai Hospital. Granulomas usually become calcified over time, meaning that they have the same density as bone. Granulomas are often discovered incidentally by a chest X-ray after they have calcified.
If surgery is recommended to remove the calcified granuloma, it can be done in two ways. Open lung surgery or thoracotomy uses a large incision in the chest wall, through which a surgeon removes the affected portion of the lung, says WebMD. A procedure called video-assisted thoracoscopic surgery involves the insertion of a camera through a small incision in the chest. This allows the surgeon to visualize the area and perform the surgery without using a large chest incision. Recovery time for this procedure is faster than for open lung surgery.
