Pulmonary nodules present a diagnostic challenge when they appear as atypical metastases in pediatric oncology patients. Chest computed tomography (CT) is the primary imaging modality for assessing lung nodules. In pediatric populations, Wilms tumor and osteosarcoma are the cancers most likely to produce pulmonary metastasis, both typical and atypical. This pictorial essay provides a thorough description of the specific radiologic features of atypical pediatric pulmonary metastases, and their pathogenesis and differential diagnosis. We also address diagnostic approaches to incidental lung nodules in healthy children found in the literature. Our aim is to help radiologists identify atypical lung metastases on CT, ensuring that children receive prompt, and potentially lifesaving, treatment.
当肺部结节在儿科肿瘤患者中表现为非典型转移时，会带来诊断上的挑战。胸部计算机断层扫描（CT）是评估肺部结节的主要影像学手段。在儿科人群中，Wilms 瘤和骨肉瘤是最有可能产生肺部转移的癌症，包括典型和非典型转移。本文通过图像形式全面描述了非典型性儿科肺部转移的特定放射学特征及其发病机制和鉴别诊断。我们还讨论了文献中健康儿童偶然发现肺部结节的诊断方法。我们的目的是帮助放射科医生在 CT 上识别非典型性肺转移，以确保儿童得到及时的、可能挽救生命的治疗。
