目的研究肺炎衣原体肺炎暴发流行的胸部影像学特征表现。方法对经过痰和咽试子标本,PCR,MIF检测证实的15例暴发流行的肺炎衣原体肺炎住院患者胸部X线和高分辨CT表现进行分析。结果本组暴发流行的肺炎衣原体肺炎患者均有发热,头痛,全身肌肉酸痛,干咳,声音嘶哑,咽痛等症状。肺部呼吸音减低或细湿啰音4例(26.7%),出现明显肺部影像学表现10例(66.7%)。10例暴发流行的肺炎衣原体肺炎常表现为多发或单发以小叶为中心阴影和腺泡状结节影(100%),病变以两中、下肺叶,外、中带分布;以小叶分布的气腔实变和磨玻璃样阴影(分别为100%和40%)和支气管血管束增厚(90%)。无肺门或纵隔淋巴结增大和胸腔积液。结论暴发流行的肺炎衣原体肺炎具有群体发病,临床和影像学表现有相似的特征,早期CT检查更能真实地反映病变大小、多少和分布范围。
Objective To study the chest radiographic features of the outbreak of Chlamydia pneumoniae pneumonia. Methods Thorax X-ray and high-resolution CT findings of 15 outpatients with pneumonia chlamydia pneumonia confirmed by sputum and pharyngeal samples, PCR and MIF were analyzed. Results Outbreaks of this group of patients with Chlamydia pneumoniae pneumonia were fever, headache, muscle soreness, dry cough, hoarseness, sore throat and other symptoms. 4 cases (26.7%) had pulmonary breath sounds reduced or fine wet rales, and 10 cases (66.7%) had obvious pulmonary imaging findings. The 10 outbreaks of pneumonia chlamydia pneumonia often manifested as multiple or solitary with lobular as the center of the shadow and acinar nodules (100%), the lesion in the two lobes, the outer lobe, the distribution; lobular distribution Air cavity consolidation and ground glass-like shadows (100% and 40%, respectively) and thickening of the bronchovascular bundle (90%). No hilar or mediastinal lymph nodes increased and pleural effusion. Conclusions The outbreaks of pneumonia chlamydia pneumonia have group onset. Clinical and imaging findings have similar characteristics. Early CT examination can more accurately reflect the size, size and distribution of lesions.
