【摘要】：目的:探讨艾滋病相关肺部恶性肿瘤的CT表现特征。方法:回顾性分析8例艾滋病合并肺部恶性肿瘤患者的CT表现。结果:4例卡波西肉瘤中3例表现为支气管血管束增粗、小叶间隔增厚,多个沿支气管血管束分布的结节、纵隔、腋窝或肺门淋巴结肿大,双侧胸腔积液,1例主要表现为结节;1例淋巴瘤为单发肿块,病灶内可见坏死及空气支气管征,增强扫描呈轻度不均匀强化;3例肺癌均为明显强化的孤立肿块,腺癌为形态不规则的外周型肿块伴肺内转移,鳞癌和小细胞癌为中央型肿块,前者可见阻塞性肺炎、肺不张及病灶侧肺门淋巴结肿大,后者纵隔及病灶侧肺门淋巴结显著肿大,3例病灶侧均可见胸腔积液。结论:艾滋病合并肺内恶性肿瘤的CT表现具有一定特征性,CT检查对其诊断及鉴别诊断具有重要价值。
[Abstract]:Objective: to investigate the CT features of AIDS-associated pulmonary malignancies. Methods: Ct findings of 8 AIDS patients with pulmonary malignant tumors were retrospectively analyzed. In 4 cases of Kaposi's sarcoma, 3 cases showed thickening of bronchovascular tract. Interlobular septum thickened, multiple nodules distributed along bronchovascular bundles, mediastinum, axillary or hilar lymph nodes enlarged, bilateral pleural effusion in 1 case showed nodules; One case of lymphoma was a single mass with necrosis and air bronchus sign in the lesion and slight uneven enhancement on enhanced scan. 3 cases of lung cancer were obviously enhanced solitary mass, adenocarcinoma was irregular peripheral mass with intrapulmonary metastasis, squamous cell carcinoma and small cell carcinoma were central mass, obstructive pneumonia was seen in the former. Atelectasis and hilar lymph node enlargement, mediastinal and focal hilar lymph node enlargement. The pleural effusion was found in 3 cases. Conclusion: Ct findings of AIDS complicated with lung malignant tumor have some characteristic CT features and have important value in the diagnosis and differential diagnosis of AIDS.

【正文快照】： 人类免疫缺陷病毒(human immunodeficiency vi-rus,HIV)感染损害机体免疫功能,导致肿瘤发病率增加[1,2]。肺是艾滋病肿瘤常见的累及部位,目前影像学研究较少。本文回顾性分析8例艾滋病合并肺部恶性肿瘤患者的CT表现,旨在探讨CT对该类病变的诊断价值。材料与方法1.病例资料搜集
