【摘要】：目的分析小儿支原体肺炎的胸部CT影像学特征。方法对2015年1月至2016年1月北京市上地医院儿科收治的126例确诊为支原体肺炎患儿的临床资料进行回顾性研究,患儿均进行了胸部螺旋CT检查,并由3名医师对造影结果进行分析。结果 126例患儿的CT影像形态表现以磨玻璃密度斑片影为主[77.8%(98例)],其次为网格结节影[58.7%(74例)]和实变影[57.9%(73例)],肿块影最少[4.0%(5例)];患儿肺部特点表现为以支气管充气征和淋巴结肿大为主,分别62例(49.2%)、59例(46.8%),其次为支气管壁增厚[37.3%(47例)]和胸膜改变[35.7%(45例)],肺不张例数最少[10例(7.9%)];肺炎患儿的病变特点为单侧肺炎(66.7%,84例)多于双侧肺炎(33.3%,42例),单叶段病变(57.9%,73例)略高于双叶段病变(42.1%,42例);患儿肺部(左肺、右肺和双肺)受累情况分别为31.0%(39例),35.7%(45例)和33.3%(42例)。结论小儿支原体肺炎有影像学特点明显,分析小儿胸部CT影像学特点有助于小儿支原体肺炎早期的辅助诊断。
[Abstract]:Objective to analyze the chest CT imaging features of mycoplasma pneumonia in children. Methods the clinical data of 126 children with mycoplasma pneumonia admitted to the Department of Pediatrics of Shangdi Hospital from January 2015 to January 2016 were retrospectively studied. All the children were examined by chest spiral CT. The results of angiography were analyzed by 3 physicians. Results the CT findings were mainly ground glass density spots (77.8%, 98 cases), followed by grid nodules (58.7%, 74 cases) and solid images (57.9%, 73 cases). The tumor shadow was the least [4.0% (5 cases)]; The pulmonary features were mainly bronchus inflation sign and lymph node enlargement, 62 cases (49.2%), 59 cases (46.8%), respectively. Bronchial wall thickening [37.3% (47 cases)] and pleural changes [35.7% (45 cases)] were followed by the lowest number of atelectasis [10 cases (7.9%)]. The pathological features of children with pneumonia were unilateral pneumonia (66.7%, 84 cases) more than bilateral pneumonia (33.3%, 42 cases). The lesion of unilateral segment (57.9%, 73 cases) was slightly higher than that of bilateral segment (42.1%, 42 cases). The incidence of lung involvement (left lung, right lung and bilateral lung) was 31.0% (39 cases), 35.7% (45 cases) and 33.3% (42 cases), respectively. Conclusion the imaging features of mycoplasma pneumonia in children are obvious. The analysis of chest CT imaging features in children is helpful to the early auxiliary diagnosis of mycoplasma pneumonia in children.
