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。
Objective：The purpose of this study was to investigate the CT features of AIDS-related pulmonary malig-nant tumors.Methods：CT findings of eight patients of AIDS with pulmonary malignant tumors confirmed by pathology were retrospectively analyzed and summarized.Results：Four out of the eight cases were Kaposi sarcoma,three of which presented as thickened bronchovascular bundles and interlobular septum,nodules distributing along the bronchovascular bundles,me-diastinal,hilar or axillary lymphadenopathy,and bilateral pleural effusions.One case was lymphoma showing single mass with mild heterogeneous enhancement inside,which had necrosis and air bronchogram.The other three cases were lung cancer with obvious contrast enhancement.One was adenocarcinoma showing as a peripheral irregular mass with intrapul-monary metastases.The other two cases were squamous cell carcinoma and small cell carcinoma showing as central type ne-oplasms.There were pulmonary atelectasis and obstructive pneumonia accompanied by hilar lymphadenopathy on the same side in squamous cell carcinoma and obvious mediastinal and bilateral hilar lymphadenopathy in small cell carcinoma.Pleural effusion was seen on the lesion side in all the three cases.Conclusion：Pulmonary malignant tumors in AIDS patients have some typical CT imaging features and CT plays an important role in the diagnosis and differential diagnosis.
