【摘要】 目的　分析艾滋病 (AIDS)合并卡氏肺囊虫肺炎 (PCP)的影像学特征。方法　收集 11例血液HIV抗体阳性 ,且临床诊断为PCP患者 (并经病理证实 )的临床资料。影像学观察采用X线胸片 ,其中 9例行CT检查。结果　 11例患者的肺部均表现为弥漫性病变。其中 ,9例肺呈小叶浸润 ,病变肺叶为毛玻璃状 ,双肺可见广泛分布的网结节状影 ,其结节直径≤1cm ,沿小叶中心分布 ,病变由肺门向肺外带发展 ,自下肺逐渐向上肺蔓延。大叶实变 2例 ,表现为一叶或多叶实变 ,伴有肺气囊改变。结论　卡氏肺囊虫肺炎具有特征性影像学改变 ,影像学检查可达到鉴别诊断的目的 ,可代替病原学检查更多还原

【Abstract】 objective To analyze the radiological features of the pneumocysis carinii pneumonia in AIDS. Methods Collect the clinical information of 11 cases which were diagnosed as PCP and were HIV antibody sercpositive. All cases adopted plan chest radiology and computed tomography (CT) was performed in 9 cases. Results Diffuse pulmonary infiltration was observed in 11 cases, while 9 patients showed lobule soakage. The lobule soakaged was ground glass attenuation. We observed that multiple, irregular nodules (D≤1cm) in both sides of the lung field. It had a centrilobular distribution of nodules. PCP expanded from inferior lobe to upper lung. Two cases had lobar consolidation. Predominant findings included solid infiltration (one or multiple lobar) and multiple thin wall cysts common. Conclusion PCP had a typical chest X ray and CT findings. The pulmonary radiological signs can help to find out the potential infections cause.更多还原
