目的:探讨艾滋病合并卡氏肺孢子虫肺炎的CT表现。方法:随机选取我院接受CT检查的12例艾滋病合并卡氏肺孢子虫肺炎患者,所有患者均行CT检查,并对患者CT检查结果进行回顾性分析。结果:4例(33.33%)患者出现渗出性毛玻璃状影,主要特点为双肺散在弥漫性毛玻璃状密度增高影,且对称分布于两肺门,肺尖部视野相对清晰。2例(16.67%)患者出现间质型性实变影,主要特点为双肺纹理增粗,且不清晰,散在少许斑片状密度增高影。2例(16.67%)患者出现渗出性斑片状影,主要特点为双肺纹理较为粗乱,且可观察到较多斑片状密度增高影,斑片大小不一。3例(25.00%)患者出现粟粒性改变,双肺出现大量大小不一粟粒状阴影,分布范围较为广泛。1例(8.33%)患者出现气囊性病变,主要特点为于患者肺门内可见数个囊形影,多呈对称分布,囊壁较薄且光滑,囊内无内容物。结论:针对艾滋病合并卡氏肺孢子虫肺炎的患者,有效掌握艾滋病合并卡氏肺孢子虫肺炎的典型CT表现,对及时诊断和治疗该病具有重要的临床价值。 Objective: To explore the CT manifestations of AIDS with Pneumocystis carinii pneumonia. Methods: Twelve AIDS patients with Pneumocystis carinii pneumonia were randomly selected from our hospital for CT examination. All patients underwent CT examination. The CT findings of the patients were retrospectively analyzed. Results: Four cases (33.33%) of patients with exudative frosted glass, the main feature of the diffuse double lung diffuse frosted glassy density, and the symmetry in the two hilar, the lung apex clear vision. Two cases (16.67%) patients with interstitial degeneration, the main features of lungs thickening of the lungs, and not clear, scattered in a little patchy density increased shadow. Two patients (16.67%) had exudative patchy features. The main feature was that the lungs were relatively rough, and more patchy densities were observed, with patch sizes varying. Three patients (25.00%) had miliary changes, a large number of moth-shaped shadows appeared in both lungs, and their distribution range was wider. One patient (8.33%) had cystic lesions. The main features were several cysts in the hilar of the patient, mostly symmetrical distribution, thin and smooth cystic wall with no contents in the cysts. Conclusions: To effectively understand the typical CT findings of AIDS complicated with Pneumocystis carinii pneumonia in patients with AIDS complicated with Pneumocystis carinii pneumonia, it has important clinical value in diagnosing and treating Pneumocystis carinii pneumonia.
