摘要
Chordoma as a rare malignant tumor arising from remnants of the fetal notochord accounts for 1%-4%of primary bone tumors. It is usually predominant in males. Local recurrences are common （44%-78%） and distant metastases may occur years after the initial presentation. The reported rates of metastases range from 10% to 48%, which are usually accompanied by a sacrococcygeal chordoma. Cases of surgical seeding and intradural spinal seeding also have been reported climcally. To our knowledge, the present case is the first one concerning cerebrospinal fluid metastases and fatal progression of a sacrococcygeal chordoma.
