ABSTRACT
Objective To study the MSCT findings of pulmonary lymphoma,and improve its imaging diagnostic accuracy.Methods The MSCT findings of 14 patients with pathologically proven pulmonary lymphoma were reviewed retrospectively.Evaluated imaging findings included distribution position,number,shape,density and accompanying signs of the lesion.Results In 14 cases of pulmonary lymphoma,except for miliary shadow,there were 108 lesions,including small nodules,nodules,masses,consolidation,ground-glass density and meshlike shadow.Solitary lesions were founded in 2 and multiple lesions were founded in 12 of 14 cases,which the multiple lesions found in single lung in 3 cases,and multiple lesions found in both lungs in 9 cases.There were 24 lesions in 7 cases of pulmonary consolidation, including air bronchogram in 6 cases and bronchiectasis in 3 cases.There were 7 cases with masses,5 cases with nodules,5 cases with small nodules,2 cases with ground-glass density,2 cases with pulmonary interstitial changes,2 cases with CT angiogram sign,4 cases with pleural effusion and 3 cases with mediastinal or pulmonary hilar lymphadenopathy.Conclusion The mainly MSCT findings of pulmonary lymphoma was pulmonary consolidation with air bronchogram,or masses,or nodules,or multiple signs exist at the same time.The diagnosis is mainly based on histopathology.
