MR imaging has evolved as the primary modality for imaging spinal neoplasms; however, neoplasms must be distinguished from unusual appearances of degenerative lesions. This article reviews MR imaging findings of a variety of neoplastic lesions of the lumbar spine. For example, extradural, metastatic tumors are the most common; nerve sheath tumors are the most common intradural extramedullary tumors; and ependymoma accounts for most of the tumors arising from the filum terminale.
磁共振成像（MR）已发展成为脊柱肿瘤成像的主要方式；然而，肿瘤必须与退行性病变的异常表现相区分。本文回顾了腰椎各种肿瘤性病变的MR成像表现。例如，硬膜外转移性肿瘤最为常见；神经鞘瘤是最常见的硬膜内髓外肿瘤；而室管膜瘤占终丝来源肿瘤的大多数。
