Abstract:
Chordoma is a rare vertebral tumor that develops from the chorda. The high malignant potential of this tumor, which is associated with a poor life prognosis, has been recognized particularly in the case of tumors originating at the mobile spine. In recent years, en bloc resections of such tumors and an increasing emphasis on a complete local cure have resulted in a certain degree of improvement in the prognosis. This case concerns a 61-year-old male with an L2 chordoma on whom en bloc spondylectomy was performed using a combined anterolateral retroperitoneal, and posterior approach. During the follow-up period, since the transplanted bone was fractured and the rod was broken, a reoperation was performed. Although the surgical margin became intralesional, a favorable course without any metastasis or recurrence during a 10-year postoperative follow-up has been observed. The presenting symptoms, imaging studies, and related literature are reviewed in this report. Thus, the method used in this case may also be considered potentially effective in achieving a radical cure in advanced cases with a local recurrence.
