Tumores primarios de columna

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.
