Pneumonia is an infectious disease of the lung causing mortality. Mycoplasma pneumonia (MP) is an atypical bacterial pneumonia that damages several organs. Lung computed tomography (CT) has been utilized in its identification. The aim of the present study was to examine the value of computed tomography diagnosis for pediatric MP. The present study prospectively analyzed the clinical and imaging data of 1,280 cases of pediatric MP in the out- and inpatient departments from March, 2010 to March, 2014; analyzed the morphology and distribution of the pneumonic lesion in the lungs; and summarized the value of CT diagnosis for pediatric MP. In the included children, there were 688 cases of lesions in the unilateral lobe, 592 cases of lesions in the bilateral lobes, 1,101 cases of extensive patchy opacity, 496 cases of mottled opacity, 432 cases of increased lung marking, 256 cases of streak opacity, 192 cases of ground-glass opacity, 992 cases of thickened bronchial wall in the lesions, 128 cases of lymphadenopathy in the hilar lymph nodes and mediastinal lymph nodes, and the lung CT showed 32 cases of pulmonary cavity and 144 cases of pleural effusion. In conclusion, the CT signals of pediatric MP had several types with some children exhibiting complicated changes. The child's clinical manifestation and symptoms should thus be considered in the diagnosis to improve the diagnostic rate.
肺炎是一种可导致死亡的肺部感染性疾病。支原体肺炎（MP）是一种可损害多个器官的非典型细菌性肺炎。肺部计算机断层扫描（CT）已被用于其诊断。本研究的目的是探讨CT诊断小儿MP的价值。本研究前瞻性分析了2010年3月至2014年3月期间门诊和住院部1280例小儿MP的临床和影像资料；分析了肺部肺炎性病变的形态和分布；总结了CT诊断小儿MP的价值。纳入的患儿中，单侧肺叶病变688例，双侧肺叶病变592例，广泛斑片状模糊影1101例，斑点状模糊影496例，肺纹理增多432例，条索状模糊影256例，磨玻璃样模糊影192例，病变处支气管壁增厚992例，肺门淋巴结及纵隔淋巴结肿大128例，肺部CT显示肺空洞32例，胸腔积液144例。综上所述，小儿MP的CT表现具有多种类型，部分患儿存在复杂变化。因此，在诊断时应结合患儿的临床表现和症状，以提高诊断率。
