Mycoplasma pneumoniae is a major cause of community-acquired pneumonia. Because most children are not imaged prior to onset of clinical symptoms, the appearance of early Mycoplasma infection has not been extensively studied. We present the case of an 11-year-old boy with large pulmonary masses incidentally detected during spine MRI evaluation for scoliosis. Eight days later, the patient developed acute respiratory symptoms, and the masses seen previously had evolved into a diffuse bronchiolitis. Diagnostic testing identified Mycoplasma pneumoniae as the likely etiology. We briefly review chest CT findings of infection by Mycoplasma and compare them to this unusual presentation of Mycoplasma pneumonia with subclinical imaging findings.
肺炎支原体是社区获得性肺炎的主要病因。由于大多数儿童在临床症状出现之前未进行影像学检查，早期支原体感染的表现尚未得到广泛研究。我们报告一例11岁男孩的病例，该男孩在因脊柱侧弯进行MRI评估时偶然发现肺部有巨大肿块。八天后，患者出现急性呼吸道症状，之前所见的肿块已演变为弥漫性细支气管炎。诊断检测确定肺炎支原体为可能的病因。我们简要回顾肺炎支原体感染的胸部CT表现，并将其与这种伴有亚临床影像学表现的不寻常肺炎支原体肺炎表现进行比较。
