目的 探讨艾滋病(AIDS)合并卡 氏肺囊虫肺炎(PCP)的螺旋CT表现及鉴别 诊断。方法 对我院经临床及病理证实的 62例AIDS合并PCP患者的螺旋CT影像学 资料进行回顾性分析，并对其影像学特 点进行分析总结。结果 62例患者螺旋CT 表现为磨玻璃状影62例(100%)，肺泡实 变影20例(32.26%)，间质型实变影19例 (30.65%)，网织结节影14例(22.58%)，肺 气囊9例(14.52%)。少见的合并表现为粟 粒样改变、纵隔或肺门淋巴结肿大、气 胸、胸腔积液、心包积液。结论 双肺磨 玻璃状影、肺泡实变影、间质型实变影、 网织结节影是AIDS合并PCP的特征性表 现，AIDS患者在合并上述CT征象时，应考 虑可能合并PCP，并及时给予确认及早期 治疗。

Objective To investigate CT findings and differential diagnosis of AIDS combined combined pneumocystis carinii pneumonia spiral. Methods Spiral CT imaging data of 62 cases of AIDS patients with PCP combined helical CT imaging confirmed by clinical and pathology in our hospital were retrospectively analyzed. Results 62 patients spiral CT showed ground glass Movies 62 cases (100%), alveolar opacities 20 cases (32.26%), interstitial opacities 19 cases (30.65%), reticulocyte nodules 14 cases (22.58%), pulmonary balloon 9 cases (14.52%). Rare combined performance of miliary changes, mediastinal or hilar lymphadenopathy, pneumothorax, pleural effusion, pericardial effusion. Conclusion Lung ground glass shadow, alveolar opacities, interstitial opacities, reticular nodules PCP in AIDS patients is characteristic manifestation, AIDS patients when combined CT signs above, should consider the possible merger PCP, and timely recognition and early treatment.
