Spinal tumors consist of a large spectrum of various histologic entities. Multiple spinal lesions frequently represent known metastatic disease or lymphoproliferative disease. In solitary lesions primary neoplasms of the spine should be considered. Primary spinal tumors may arise from the spinal cord, the surrounding leptomeninges, or the extradural soft tissues and bony structures. A wide variety of benign neoplasms can involve the spine including enostosis, osteoid osteoma, osteoblastoma, aneurysmal bone cyst, giant cell tumor, and osteochondroma. Common malignant primary neoplasms are chordoma, chondrosarcoma, Ewing sarcoma or primitive neuroectodermal tumor, and osteosarcoma. Although plain radiographs may be useful to characterize some spinal lesions, magnetic resonance imaging is indispensable to determine the extension and the relationship with the spinal canal and nerve roots, and thus determine the plan of management. In this article we review the characteristic imaging features of extradural spinal lesions.
脊柱肿瘤包含众多不同组织学类型的病变。多发脊柱病变常提示已知的转移性疾病或淋巴增殖性疾病。对于孤立性病变，应考虑脊柱原发性肿瘤。原发性脊柱肿瘤可起源于脊髓、周围软脑膜或硬膜外软组织及骨结构。多种良性肿瘤可累及脊柱，包括骨岛、骨样骨瘤、骨母细胞瘤、动脉瘤样骨囊肿、巨细胞瘤和骨软骨瘤。常见的原发性恶性肿瘤有脊索瘤、软骨肉瘤、尤因肉瘤或原始神经外胚层肿瘤以及骨肉瘤。尽管平片对某些脊柱病变的特征性诊断可能有用，但磁共振成像对于确定病变范围及其与椎管和神经根的关系、进而确定治疗方案是必不可少的。在本文中，我们将回顾硬膜外脊柱病变的特征性影像表现。
