脊柱肿瘤由多种组织学实体组成。多发性脊柱病变通常代表已知的转移性疾病或淋巴增生性疾病。在孤立性病变中，应考虑脊柱的原发肿瘤。原发脊柱肿瘤可发生于脊髓、周围的软脑膜或硬膜外软组织和骨结构。多种良性肿瘤可累及脊柱，包括内生症、骨样骨瘤、成骨细胞瘤、动脉瘤性骨囊肿、巨细胞瘤和骨软骨瘤。常见的恶性原发肿瘤有脊索瘤、软骨肉瘤、尤文肉瘤或原始神经外胚层肿瘤和骨肉瘤。虽然平片可能有助于确定某些脊柱病变的特征，但磁共振成像对于确定病变的范围以及与椎管和神经根的关系，从而确定治疗方案是必不可少的。在本文中，我们回顾了硬膜外脊柱病变的影像特征。
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.
