目的对小儿肺炎支原体肺炎的CT特征进行分析,探讨小儿肺炎支原体肺炎肺部CT影像学特点。方法选择罗山县人民医院2011年3月至2014年3月收治的322例小儿肺炎支原体肺炎患儿予以CT检查,并对全部患儿肺部CT影像学特点及其与年龄及临床表现之间的关系进行统计分析。结果全部患儿单侧病变占50.6%;双侧病变占49.4%;全部患儿的支气管壁增厚占78.0%;支气管壁充气占63.0%;磨玻璃样影占14.9%;支气管“树芽”征占31.7%;肺实变占40.7%;斑片状影占41.0%;纵隔淋巴结肿大占12.7%;胸腔积液占14.0%。且3岁以下患儿磨玻璃样影病灶和斑片状影的发生率显著高于3岁及以上患儿(P<0.01),而其支气管“树芽征”、肺实变及胸腔积液的发生率显著低于3岁及以上患儿(P<0.05)。在临床表现上,CT征象表现为支气管壁增厚及支气管“树芽征”的患儿均存在不同程度的发热咳嗽。肺实变和胸腔积液患儿均出现持续高热。斑片状影的患儿临床上均表现为分泌物较多。结论小儿肺炎支原体肺炎肺部CT征象表现类型多样,部分患儿肺部合并多种CT征象,结合患儿的年龄及临床表现能够提高小儿肺炎支原体肺炎的确诊率。
Objective To analyze the CT features of children with Mycoplasma pneumoniae pneumonia and explore the characteristics of pulmonary CT in children with Mycoplasma pneumoniae pneumonia. Methods A total of 322 children with mycoplasma pneumoniae pneumonia admitted from March 2011 to March 2014 in Luoshan County People’s Hospital were enrolled in this study. CT features of lung CT images of all children and their relationship with age and clinical manifestations The relationship between statistical analysis. Results All children with unilateral lesions accounted for 50.6%; bilateral lesions accounted for 49.4%; all children with bronchial wall thickening accounted for 78.0%; bronchial wall inflation accounted for 63.0%; ground glass-like shadow accounted for 14.9%; bronchial “31.7% of levy; lung consolidation accounted for 40.7%; patchy film accounted for 41.0%; mediastinal lymph nodes accounted for 12.7%; pleural effusion accounted for 14.0%. The incidence of ground-glass lesions and patchy lesions in children younger than 3 years was significantly higher than that in children aged 3 years and older (P <0.01), while the bronchial tree buds, lung consolidation and pleural cavity The incidence of effusion was significantly lower in children aged 3 years and older (P <0.05). In clinical manifestations, CT signs of bronchial wall thickening and bronchial ”tree bud sign" in children with varying degrees of fever cough. Pulmonary consolidation and pleural effusion in children with sustained high fever. Patchy shadow of children are clinically manifested more secretions. Conclusions There are many types of pulmonary CT findings in children with Mycoplasma pneumoniae pneumonia. Some children with pulmonary CT complicated with various CT signs can improve the diagnosis rate of pneumonia mycoplasma pneumonia in children with their age and clinical manifestations.
