目的探讨艾滋病合并马红球菌 感染患者的X线及CT影像表现。方法 回顾 性分析10例艾滋病合并马红球菌感染患 者的影像学表现。结果 X线胸片见团块 高密度阴影5例,斑片状、片状渗出实变4 例, 病灶内见空洞5例、胸腔积液3例。CT 显示大面积(叶、段分布)实变8例，周边 见斑片状渗出实变9例、空洞9例(8例见液 平)、邻近胸膜粘连7例、胸腔积液4例、 结节灶8例、支气管气像7例、纵隔淋巴结 肿大3例、支气管扩张1例。结论 肺浸润 实变并空洞形成,邻近胸膜增厚粘连及散 发结节是艾滋病合并马红球菌肺炎的常见 胸部影像表现。

Objective To study the imaging appearances of Rhodococcus equi pneumonia of ten Patients with Acquired immunodeficiency syndrome (AIDS). Methods Thoracic imaging appearances of Rhodococcus equi pneumoniain of ten patients with AIDS were retrospectively analyzed. Results The chest radiograph showed patchy consolidations (n=4), mass shadow with high density (n=5). irregular cavity(n=5), pleural effusion(n=3). CT showed large lobar(n=8), patchy consolidations(n=9), irregular cavity (n=9)(8case have air-fluid level), adjacent pleural thickening (n=7), leural effusion(n=4), nodules(n=8), air bronchogram (n=7), Mediastinal lymph node enlargement(n=3), ronchiectasis(n=1). Conclusion The most common radiological in AIDS patients with Rhodococcus equi pulmonary infection are Large consolidations with multiple cavitations and pleural thickening, multiple centrilobular nodules.
