【摘要】 目的 探讨鹦鹉热衣原体肺炎患者的CT表现特征。方法 回顾性分析笔者医院经宏基因二代测序（macrogene second-generation sequencing,m NGS）技术确诊10例鹦鹉热衣原体肺炎患者的胸部CT图像。结果 7例（70%）患者与鸟（禽）类或其粪便有接触史。入院胸部CT均表现为团片状渗出实变影，均位于单肺，其中累及单叶8例（80%）、双叶2例（20%）;10例（100%）均伴有支气管充气征，9例（90%）有磨玻璃影，8例（80%）局部小叶间隔或小叶内间隔增厚；1例（10%）病灶呈“扇形”改变，1例（10%）病灶见“反晕症”，9d内复查9例（90%）有进展，表现为病灶融合增大呈更大范围实变或新出现病灶。结论 鹦鹉热衣原体肺炎CT表现具有一定特征，结合鸟（禽）类接触史可提示诊断。更多还原

【Abstract】 Objective To investigate CT features of Chlamydia psittaci(C. psittaci) pneumonia patients. Methods Ten patients with C. psittaci pneumonia were collected retrospectively based on macro gene second-generation sequencing(mNGS). The radiological manifestations of the disease were analyzed. Results Seven patients(70%) had contact history with birds(poultry) or their feces. Chest CT on the day of admission was mainly mass patchy consolidation, all of which were located in single lung,involving 8 cases(80%) with one lobe and 2 cases(20%)with two lobes. All of them were accompanied by air bronchogram, 9cases(90%)with ground glass shadow and 8 cases(80%)with interstitial changes. One case(10%)showed a reversed halo sign, and 1 case(10%) showed fan-shaped consolidation. Nine cases(90%) showed progress with increased fusion or new lesions within nine days. Conclusion CT findings of C. psittaci pneumonia have certain characteristics, and combining with history of contacting birds(poultry) can suggest diagnosis.更多还原
