Lung nodules or small masses of
tissue in the
lung may be due to infections, such as histoplasmosis or tuberculosis, hamartoma,
lung cysts, and vascular abnormalities as well as possible malignancy. While neoplasm is a possibility, this is not yet confirmed. Other differentials mentioned in the result are scar tissue and possibly caused by inflammation. Additional diagnostic tests may need to be done to rule out malignancy.
