Methods The dats of totally 20 patients with secondary pulmonary lymphoma which were proven through lung puncture pathology or clinical treatment were retrospectively analyzed. There were 19 non-Hodgkin lymphoma cases and 1 Hodgkin lymphoma case. All cases received thorax CT scanning, and 13 of them had enhanced CT scanning. Results There were many patterns in our CT findings for secondary pulmonary lymphoma, mixed pattern in 9 cases, mass (nodule) in 4 cases, pneumonic-alveolar in 3 cases, bronchovascular-lymphatic in 3 cases, and miliary in 1 case. There were 13 cases accompanying with mediastinal lymphadenovarix, 5 cases with pleura invasion, 11 cases with pleural effusion, and 2 cases with pericardium involvement. Mild enrichment was found in 7 cases and obviously enrichment was seen in 1 case. Conclusion Diversity is the characteristic feature of secondary pulmonary lymphoma. Combined with other thorax findings, CT scaning can make a definite diagnosis.
