良性脊索细胞瘤(benign notochordal cell tumor,BNCT)是一种来源不明的脊椎内良性病变,临床罕见,到目前为止,国内外文献报道25例[1~11]。该病变大多局限在椎体内,患者一般不出现症状或者症状轻微,普通X线检查常难以发现,仅在因其他原因切除的脊椎内或在活检时偶尔才被发现,且一般不需要手术治疗[4、8]。由于其在影像学、组织病理学等方面与脊索瘤相似,容易被误诊,并最终 Benign notochordal cell tumor (benign notochordal cell tumor, benign notochordal cell tumor, benign notochordal cell tumor is an unknown source of benign spinal lesions, the clinical rare, so far, 25 cases reported in the literature [1-11]. The lesion is mostly confined to the vertebral body. The patient is generally free from symptoms or mild symptoms. Common X-ray findings are often difficult to detect, only occasionally found in spine resected for other reasons or on biopsies, and generally require no surgical treatment [4,8].
