We aim to review the imaging appearance of primary bony tumors of the spine and simulating lesions. Benign bone tumors commonly appear as well-circumscribed, slow-growing lesions with a calcified or sclerotic matrix. Malignancy is often aggressive permeative lesions with bone destruction, cortical invasion and associated soft-tissue mass. CT is an excellent imaging modality for characterization of the tumor matrix, exact location, extension and osseous changes, while MR imaging is superior for evaluation of the associated soft-tissue mass, bone marrow infiltration and intraspinal extension. There is a spectrum of pseudotumors that may also involve the spine. The imaging appearance of primary spinal bone tumor in conjunction with the patient's age, gender and lesion location allows a high percentage of correct diagnosis. Imaging plays an important role in diagnosis, characterization and extension of bone tumors of the spine which will help guide therapy.
我们旨在回顾脊柱原发性骨肿瘤和模拟病变的影像学表现。良性骨肿瘤通常表现为边界清楚、生长缓慢的病变，具有钙化或硬化基质。恶性肿瘤通常是侵袭性的弥漫性病变，伴有骨破坏、皮质侵犯和相关的软组织肿块。CT 是一种极好的成像方式，可用于描述肿瘤基质、准确位置、扩展和骨变化，而磁共振成像（MR 成像）则更适合评估相关的软组织肿块、骨髓浸润和椎管内扩展。还有一系列可能也涉及脊柱的假性肿瘤。结合患者的年龄、性别和病变部位，原发性脊柱骨肿瘤的影像学表现可实现高比例的正确诊断。影像学在脊柱骨肿瘤的诊断、特征和扩展中起着重要作用，有助于指导治疗。
