The objective of this study was to assess the computed tomography (CT) features of Mycoplasma pneumoniae pneumonia. We retrospectively reviewed CT findings of 16 patients (M:F = 9:7, age range 1-74 years, median 9 years) with serologically proven Mycoplasma pneumoniae pneumonia and with chest CT scan available. Two distinctive patterns of CT features of M. pneumoniae pneumonia were noted between the paediatric (age < 18 years) and the adult (age > or = 18 years) groups. The pediatric group (n=11) showed lobar or segmental consolidation (100%) with frequent pleural effusion (82%) and regional lymphadenopathy (82%) and mild volume decrease of the involved lobe (73%), while four of the five adult patients showed diffuse and/or multifocal, centrilobular or peribronchovascular areas of ground-glass attenuation (80%) with a lobular distribution, and frequent thickening of interlobular septa (60%) and the bronchial walls (40%) were also detected at high-resolution CT. The CT finding of a lobar or segmental consolidation with a parapneumonic effusion seen in our children with M. pneumoniae pneumonia was similar to that of bacterial lobar pneumonia. In contrast, the CT findings noted in our adult patients consisted of a mixture of a bacterial bronchopneumonia pattern and a viral interstitial pneumonia pattern.
本研究的目的是评估肺炎支原体肺炎的计算机断层扫描（CT）特征。我们回顾性分析了16例血清学确诊为肺炎支原体肺炎且有胸部CT扫描结果的患者（男:女 = 9:7，年龄范围1 - 74岁，中位数9岁）。在儿童（年龄<18岁）和成人（年龄≥18岁）组中发现了肺炎支原体肺炎CT特征的两种不同模式。儿童组（n = 11）表现为大叶或节段性实变（100%），常伴有胸腔积液（82%）和区域淋巴结肿大（82%），受累肺叶轻度体积缩小（73%），而5例成年患者中有4例表现为弥漫性和/或多灶性、小叶中心性或支气管血管周围磨玻璃影（80%），呈小叶分布，高分辨率CT还发现小叶间隔增厚（60%）和支气管壁增厚（40%）常见。我们的肺炎支原体肺炎患儿出现的大叶或节段性实变伴肺炎旁积液的CT表现与细菌性大叶性肺炎相似。相比之下，我们成年患者的CT表现为细菌性支气管肺炎模式和病毒性间质性肺炎模式的混合。
