A Giant Sacrococcygeal Chordoma: Case Report and Literature Review

摘要

Introduction: Chordomas are rare low-grade malignant lesions that are mostly seen in the spine. They constitute about 1% of intracranial tumors and 3-4% of all primary bone tumors. The principal spinal location is usually the sacrococcygeal and infrequently the sphenooccipital and cervical areas. Case Presentation: We present a 74-year-old man with a huge sacrococcygeal mass extending to both buttocks. Computerized tomography (CT-scan) and magnetic resonance imaging (MRI) as well as computerized tomographic angiography (CTA) evaluations were suggestive to chordoma. Immunohistochemical analysis confirmed the diagnosis after the patient was successfully operated on. All aggravating symptoms resolved after the operation. Conclusion: The management of giant sacrococcygeal chordomas can be very challenging but with all-inclusive treatment, complete cure is achievable although recurrence can occur. In our case, surgery alone was curative. Preoperative CTA aided us in achieving total tumor resection.
