艾滋病合并肺孢子菌肺炎的MSCT诊断

MSCT diagnosis of pneumocystis carinii pneumonia in AIDS

目的探讨多层螺旋CT对获得性免疫缺陷综合征(AIDS)合并肺孢子菌肺炎(PCP)的诊断价值。方法回顾性分析30例经临床证实的艾滋病合并肺孢子菌肺炎患者MSCT资料。结果 30例艾滋病合并肺孢子菌肺炎患者中,均有肺内透亮度减低,肺纹理增强表现,伴有弥漫磨玻璃样改变28例,地图样表现及碎石路征16例,网织状或网织小结节状改变10例,弥漫粟粒状小结节影8例,斑片状模糊影6例,肺气囊6例,肺外围"月弓征"或"柳叶征"4例,纵隔淋巴结肿大4例,右侧局限性气胸2例,双侧少量胸腔积液2例,左侧少量胸腔积液2例。结论 MSCT在艾滋病合并肺孢子菌肺炎诊断中具有重要价值。

Objective To study the diagnostic value of multislice spiral CT of acquired immunodeficiency syndrome （AIDS） associated with pneumocystis pneumonia （PCP）. Methods The MSCT materias of 30 patients with PCP in AIDS were retrospectively analyzed. All patients had been proved by clinic. Results Of the 30 patients diagnosed as PCP, all showed the derease of intrapulmonary radiolucency and the increase of lung marking, 28 showed diffuse of ground-glass change, 16 cases showed geographic performance and crazy-paving pattern, 10 cases showed change of reticular pattern or nodular pattern, 8 cases showed diffuse miliary nodules, 6 cases showed patchy fuzzy-shadow, 6 cases showed aieontai ning cystic pattern, 4 cases showed pulmonary peripheral ＂bow＂ or＂willows-sign＂, 4 cases showed mediastinum enlarge- ment of lymph nodes, 2 case showed localized pneumothorax on the right side, 2 cases showed a little of pleural effusion on the left side, and 2 cases had them on both sides. Conclusion MSCT is of great value to the diagnosis of PCP in AIDS.
