Abstract
Cartilage-forming tumors are benign cartilaginous tumors that rarely affect the spinal canal: they account for 2% of all spinal tumors and 2.6% of all benign bone tumors. Pathologically, they may be classified as chondromas, osteochondromas, chondroblastomas, and chondromyxoid fibromas. This oncotype may remain asymptomatic (it is confined within the vertebral structure) or may present as a hard paravertebral swelling (it invades the paravertebral structures) or more rarely, with a slowly-developing neurologic syndrome (it extends into the vertebral canal). Thirty-one cases have been reported (including our case) of benign cartilage-forming tumors localized in the lumbar column. Only three cases of chondroma of the lumbar spine presented with lumbar radicular pain. We report a fourth case and review clinical and radiologic characteristics of these lesions. Eleven out of the 31 cases were diagnosed as chondromas, 17 as osteochondromas, while in three cases the histopathologic diagnosis was not reported. Seventeen cases originated from the neural arch, seven from the vertebral body, two from the spinous process, and in five cases the exact localization was not reported. This tumor is more frequent in males (21 cases out of 31), t...Continue Reading
