Vertebral osteoblastoma and scoliosis. Two cases report

We report two cases of spinal osteoblastoma in two boys aged 16 and 19 year s. The lesion was disclosed by scoliosis with signs of thoracic and lumbar neurological compression. The diagnosis was provided by the CT scan and mag netic resonance imaging and was confirmed by the histology study of the sur gical specimen. Involvement of the vertebral column has been estimated to r ange from 30 to 40 % for these rare tumors that account for less than 1 % o f all bone tumors. Localization on the convex aspect of scoliosis is rare. CT-scan provides an analysis of the tumor components and clearly demonstrat es intraspinal extension. MRI is superior in visualizing neurological compr ession. In our experience, function outcome has been favorable after surgic al decompression.
