Abstract
Benign bone tumors appear as well-circumscribed lesions, often with specific tumor matrixes. Malignancy displays aggressive characteristics such as cortical erosion, bone destruction, and associated soft-tissue masses. Imaging plays an important role in diagnosis, characterization and extent of primary bone tumors of the spine as well as differ¬entiating them from simulating lesions. CT is an excellent imaging modality in characterization of the tumor matrix, origin, extension and osseous changes, while MR is superior for evaluation of associated soft tissue mass, bone marrow infiltration and intraspinal extension of the tumor the imaging appearance of bone tumor in the spine in conjunction with age, gender and location allow a high percentage of accurate diagnosis; however, biopsy is essential to reach the final diagnosis in many instances(14).
