目的 探讨AIDS合并肺癌患者的 CT影像学表现。方法 收集我院2010年1月 至2016年8月间，共约11000名艾滋病病毒 感染者的临床数据进行回顾性分析，对其 中21例病理确诊为AIDS合并肺癌患者的临 床资料及胸部CT影像表现进行分析。结果 艾滋病合并肺癌患者中腺癌13 例、鳞癌3 例，小细胞癌2例、3例病理未分型。CT影 像表现见实性肿物或结节21例；淋巴结肿 大19例，远处转移12例，胸膜受侵12例， 胸腔积液14例。结论 艾滋病合并肺癌患 者，肺部感染常见，易造成漏诊，当CT表 现为实性肿物或结节，胸膜受侵及淋巴结 肿大、胸膜明显增厚时需考虑肺癌可能。

Objective To study the CT imaging features of Lung Cancer in patients with HIV. Methods A total of 11000 HIV clinical data were collected from January 2010 to August 2016, and the clinical data and imaging data of 21 cases ofpulmonary cancer combined with HIV which were confirmed by pathology were analyzedy. Results There were 13 cases of adenocarcinoma, 3 cases of squamous cell carcinoma and 2 cases of small cell carcinoma, which combines with AIDS and lung cancer. There were 21 cases which were showed the solid masses or nodules by the CT iconography. There were 19 cases of lymph node enlargement, 12 cases of distant metastasis, 12 cases of pleura effusion and 14 cases of pleura effusion. Conclusion In AIDS patients with lung cancer, pulmonary infection is common, easy to cause missed diagnosis, when CT manifestations of pulmonary solid masses or nodules, pleural invasion, lymphadenopathy, pleural thickening need to consider the possibility of lung cancer.
