title: Primary bone tumors of the spine.
abstract: Primary bone tumors of the spine are less common than metastases or multiple myeloma. Based on the patient's age and the radiologic pattern and topography of the tumor, a very approximate differential diagnosis can be established for an osseous vertebral lesion. This article shows the radiologic manifestations of the principal primary bone tumors of the spine from a practical point of view, based on our personal experience and a review of the literature. If bone metastases, multiple myeloma, lymphomas, hemangiomas, and enostoses are excluded, only eight types of tumors account for 80% of all vertebral tumors. These are chordomas, osteoblastomas, chondrosarcomas, giant-cell tumors, osteoid osteomas, Ewing's sarcomas, osteosarcomas, and aneurysmal bone cysts.
