Benign Osteoblastomas are uncommon tumors which make up approximately 1 percent of all bone tumors. The distribution of the tumor demonstrates a high incidence for spinal involvement. This case report shows an osteoblastoma in a somewhat unusual location of the cervical spine, the posterior arch of the atlas.
良性骨母细胞瘤是一种罕见的肿瘤,约占所有骨肿瘤的1%。该肿瘤的分布显示出脊柱受累的高发生率。本病例报告展示了一例位于颈椎(寰椎后弓)这个 somewhat unusual location的骨母细胞瘤。
原文中“somewhat unusual location”直译为“有点不寻常的位置”,在医学语境下可能较难理解其确切含义,推测可能是指“相对少见的位置”等意思,由于要求不能添加解释说明,所以保留原文表述。
