We report two cases of spinal osteoblastoma in two boys aged 16 and 19 years. The lesion was disclosed by scoliosis with signs of thoracic and lumbar neurological compression. The diagnosis was provided by the CT scan and magnetic resonance imaging and was confirmed by the histology study of the surgical specimen. Involvement of the vertebral column has been estimated to range from 30 to 40% for these rare tumors that account for less than 1% of all bone tumors. Localization on the convex aspect of scoliosis is rare. CT-scan provides an analysis of the tumor components and clearly demonstrates intraspinal extension. MRI is superior in visualizing neurological compression. In our experience, function outcome has been favorable after surgical decompression.
我们报告了两例分别为16岁和19岁男孩的脊柱骨母细胞瘤病例。病变因脊柱侧弯伴胸腰椎神经受压体征而被发现。通过CT扫描和磁共振成像做出诊断，并经手术标本的组织学研究得以证实。这些罕见肿瘤占所有骨肿瘤的比例不到1%，据估计其脊柱受累率为30%至40%。位于脊柱侧弯凸侧的情况较为罕见。CT扫描可分析肿瘤成分并清晰显示椎管内扩展情况。MRI在显示神经受压方面更具优势。根据我们的经验，手术减压后功能预后良好。
