AIDS患者肺部机遇性感染的影像表现分析

Analysis on the imaging findings of patients with AIDS complicated pulmonary opportunistic infections

目的探讨AIDS患者常见肺部机遇性感染影像表现。方法收集2005年1月至2006年8月23例AIDS病合并肺部感染患者的胸部X线片及CT片,结合临床进行分析总结。结果合并肺结核13例,细菌性肺炎3例,肺部影像表现与普通肺结核、肺炎相似;卡氏肺囊虫肺炎(PCP)7例,主要表现为两肺弥漫分布斑片状、网格状、结节状影或磨玻璃样改变。结论肺部感染是AIDS病患者晚期的主要机遇性感染,影像表现对卡氏肺囊虫肺炎的诊断有重要意义。

Objective To study the common imaging findings of pulmonary opportunistic infections of patients with acquired immunodeficiency syndrome（AIDS）. Methods Twenty -three patients with clinically proved AIDS unerwent chest X - ray and CT examinations and then their imaging findings were analyzed together with the clinical data. Reasults Among 23 cases, pulmonary tuberculosis and bacterial pneumonia were found in 13 and 3 cases, respectively, Pneumocystis Caposi＇ s pneumonia（PCP） was found in 7 cases whose chest X -ray showing mottling, reticular, nodular or ground glass - like changes. Conclusion Pulmonary infection is a major opportunistic infection of the patients with AIDS at late stage. The imaging findings of patients with PCP is an important evdence for diagnosing this disease.
