目的：探讨原发性肺淋巴瘤（PPL）的 CT 表现及特征。方法对经病理证实的6例 PPL 的 CT 征象进行回顾性分析，观察肿瘤的发病部位、数目、形态、密度、伴随征象及强化特点。结果6例患者中，结节肿块型2例，肺泡或肺炎型3例，混合型1例，4例可见空气支气管征，2例跨肺叶生长；增强后大多数病灶呈中度‐明显均匀强化。结论原发性肺淋巴瘤是一种少见病，CT 表现缺乏特征性，但空气支气管征、跨叶生长、中度‐明显均匀强化的出现以及没有肺门、纵隔淋巴结肿大，可提示本病的可能，应积极行穿刺活检以明确诊断。

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 .
