Abstract：Objective To investigate the CT characteristics of primary pulmonary lymphoma .Methods 6 patients with primary pulmonary lymphoma proved by pathology were studied retrospectively .The analysis of imaging characteristics in‐cluded the position ,number ,shape ,density ,accompanying signs and enhancement features .Results Of the 6 cases ,2 cases were nodular or mass type ,3 cases were alveolar or pneumonia type ,1 case was mixed type .Air bronchogram was present in 4 cases ,2 cases showed across the lobar grow th ;Most of the cases showed moderate‐apparently homogeneous enhancement .Conclusion Primary pulmonary lymphoma is a rare disease ,and CT does not have characteristic features . But ,air bronchogram ,across the lobar growth ,moderate‐apparently homogeneous enhancement ,no hilar and mediastinal lymphadenophathy ,may be suggestive of the disease .Biopsy is recommended to confirm the diagnosis of primary pulmo‐nary lymphoma .
