Mediastinal masses are categorized based on the International Thymic Malignancy Interest Group (ITMIG) classification into prevascular, visceral and paravertebral compartments. The schema is based on cross-sectional imaging, mainly CT, and helps with generating a differential diagnosis based on location of the mass. Up to half of all pediatric mediastinal tumors are malignant. In this review we describe mediastinal masses that are relevant to the pediatric population, as well as the role of MR imaging of mediastinal masses and its advantages.
纵隔肿块根据国际胸内恶性肿瘤兴趣组（ITMIG）分类分为血管前、内脏和椎旁间隙。该方案基于横断面成像，主要是 CT，有助于根据肿块位置生成鉴别诊断。所有儿童纵隔肿瘤中多达一半是恶性的。在本综述中，我们描述了与儿科人群相关的纵隔肿块，以及纵隔肿块磁共振成像的作用及其优势。
