Lesions in the middle and posterior mediastinum are relatively rare, but there are some useful radiological clues that can be used to diagnose them precisely. It is useful to determine the affected mediastinal compartment and the locations of the main thoracic nerves on medical images for diagnosing such mediastinal lesions. Neurogenic tumors can occur in the middle mediastinum, although they generally arise as posterior mediastinal tumors. Based on the above considerations, we review various characteristic imaging findings of middle and posterior mediastinal lesions, and their differential diagnoses.

中、后纵隔病变的影像学表现。

中纵隔和后纵隔的病变相对少见，但有一些有用的放射学线索可用于准确诊断。在医学图像上确定受影响的纵隔间室和主要胸神经的位置对于诊断此类纵隔病变很有用。神经源性肿瘤可发生在中纵隔，尽管它们通常作为后纵隔肿瘤出现。基于以上考虑，我们回顾了中后纵隔病变的各种特征性影像学表现及其鉴别诊断。
