Mediastinal masses are commonly identified in the pediatric population with cross-sectional imaging central to the diagnosis and management of these lesions. With greater anatomical definition afforded by cross-sectional imaging, classification of mediastinal masses into the traditional anterior, middle and posterior mediastinal compartments - as based on the lateral chest radiograph - has diminishing application. In recent years, the International Thymic Malignancy Interest Group (ITMIG) classification system of mediastinal masses, which is cross-sectionally based, has garnered acceptance by multiple thoracic societies and been applied in adults. Therefore, there is a need for pediatric radiologists to clearly understand the ITMIG classification system and how it applies to the pediatric population. The main purpose of this article is to provide an updated review of common pediatric mediastinal masses and mediastinal manifestations of systemic disease processes in the pediatric population based on the new ITMIG classification system.
纵隔肿块在儿科人群中很常见，横断面成像对这些病变的诊断和治疗至关重要。随着横断面成像提供的解剖定义更加明确，根据侧胸射线照片将纵隔肿块分为传统的前、中、后纵隔隔室的分类方法的应用越来越少。近年来，国际胸内恶性肿瘤兴趣组（ITMIG）的纵隔肿块分类系统，基于横断面成像，已被多个胸科协会接受，并应用于成人。因此，儿科放射科医生需要清楚地了解 ITMIG 分类系统及其在儿科人群中的应用。本文的主要目的是根据新的 ITMIG 分类系统，提供对常见儿科纵隔肿块和儿科人群中全身疾病过程的纵隔表现的更新综述。
