Methods The CT materials of 18 patients with primary pulmonary lymphoma proven pathologically were retrospectively reviewed. Results Pulmonary lesions were depicted as solitary mass （n=4 cases）, nodules （n=6 cases） and multiple patchy opacities （n=8 cases）. Air bronchogram was present （n=14 cases）, interstitial infiltrates findings such as ground-glasses-like （n=11 cases）. The masses and nodules lesions showed obvious enhancement in all 10 cases who received contrasted CT scan. All 18 cases had no lymphadenopathy either in lung and mediastinal or other parts of the body.
