Objective To investigate the CT features of primary pulmonary lymphoepithelioma-like carcinoma. Methods Clinical information and CT findings were analyzed retrospectively in 14 patients with surgical pathology conformed pulmonary LELC. Results CT pulmonary LELC showed single mass,10 central tumors and 4 pripheral tumors. Among them 8 cases occurred in left lobe and 6 cases in right lobe. Fourteen tumors with diameters ranging from 1.8 to 7.3cm(mean, (5.01±2.12)cm) were identified. CT findings of pulmonary LELC consisted of well defined border,lobulation(7 cases), speculation (4 cases),vascular or bronchial encasement(5 cases), solitary punctate calcification (2 cases),obstructive pneumonia(4 cases) and lymphadenopathy in mediastinum or hilar (9 cases). On contrast-enhanced CT, 9 patients had tumors with homogeneous enhancement,and 5 tumors showed inhomogeneous enhancement. Conclusion CT findings of primary pulmonary LELC have certain characteristics, but there are some difficulties in the diagnosis of CT alone, the final diagnosis needs to rely on pathology and immunohistochemistry
