Spinal cord tumors are uncommon, and its multiple representatives not always have pathognomonic characteristics, which poses a challenge for both patients and caring physicians. The radiologist performs an important role in recognizing these tumors, as well as in differentiating between neoplastic and non-neoplastic processes, supporting clinical and surgical decision-making in patients with spinal cord injury. Magnetic Resonance Imaging (MRI) assessment, paired with a deep understanding of the various patterns of cord involvement allied to detailed clinical data can provide a diagnosis or significantly limit the differential diagnosis in most cases. In this article, we aim to review the most common and noteworthy intramedullary and extramedullary spinal tumors, as well as some other tumoral mimics, with an emphasis on their MRI morphologic characteristics.
脊髓肿瘤并不常见，其多种表现形式并不总是具有特征性，这给患者和照护医生都带来了挑战。放射科医生在识别这些肿瘤方面起着重要作用，还能区分肿瘤性和非肿瘤性病变，为脊髓损伤患者的临床和手术决策提供支持。磁共振成像（MRI）评估，结合对各种脊髓受累模式的深入了解以及详细的临床数据，在大多数情况下可提供诊断或显著缩小鉴别诊断范围。在本文中，我们旨在回顾最常见和值得注意的髓内和髓外脊髓肿瘤，以及一些其他肿瘤模拟病变，并重点介绍它们的 MRI 形态学特征。
