Chordoma is a malignant neoplasm believed to arise from notochordal remnants. It is most often found in the midline of the sacrococcygeal region (50%), skull base (35%), and the mobile spine (15%). When present in the sacral region, chordomas most often grow anteriorly. We present an unusual case of sacral chordoma with posterior extension.
脊索瘤是一种据信起源于脊索残余组织的恶性肿瘤。它最常出现在骶尾区域的中线(50%)、颅底(35%)和活动脊柱(15%)。当出现在骶骨区域时,脊索瘤最常向前生长。我们报告一例罕见的骶骨脊索瘤伴向后延伸的病例。
