1/138. A case of chordoma in association with rectal carcinoma.A 74-year-old male patient presented with anal and sacral pain 18 months after abdomino-perineal resection for rectal cancer. Computerized tomography (CT) of the pelvis demonstrated a well defined mass anterior to the lower sacrum, posteriorly infiltrating and destroying the fourth and fifth sacral nerves and invading the right gluteal fossa. A 7.5 x 15 x 2 cm encapsulated mass was demonstrated during the operation using a posterior approach and the lower sacral segments together with the tumour were removed by amputation at S3 level. Histopathology revealed chordoma. This case is unique because of the rarity of chordoma in association with rectal tumour at the sacrococcygeal region.- - - - - - - - - - ranking = 1keywords = chordoma (Clic here for more details about this article) |
2/138. Complex cervical spine neoplastic disease: reconstruction after surgery by using a vascularized fibular strut graft. Case report.The authors report a case of an aggressive chordoma in the cervical spine of a 15-year-old girl who underwent radical resection followed by reconstruction using an anterior vascularized fibular strut graft and posterior arthrodesis prior to receiving immediate postoperative radiation therapy. The patient had successful graft incorporation 4 months postoperatively. The authors review the advantages of using vascularized fibular strut grafts for the treatment of multilevel cervical spine neoplastic disease and discuss the theoretical advantages of using vascularized grafts that tolerate therapeutic levels of radiation.- - - - - - - - - - ranking = 0.16666666666667keywords = chordoma (Clic here for more details about this article) |
3/138. Vertebral intra-osseous chordoma or giant notochordal rest?Chordomas of the lumbar vertebral bodies are rare. We report an unusual case of an entirely intraosseous chordoma of the fifth lumbar vertebra treated by vertebrectomy. Conventional radiographs and scintigraphy were normal. The lesion was well visualised by MR imaging, but showed only slight sclerosis on CT. We give our reasons for making a diagnosis of chordoma rather than giant notochordal rest and discuss the problems of management resulting from this diagnostic dilemma.- - - - - - - - - - ranking = 1keywords = chordoma (Clic here for more details about this article) |
4/138. chordoma in the cervical spine managed with en bloc excision.STUDY DESIGN: En bloc resection of a chordoma in the midcervical vertebral spine was performed. OBJECTIVES: To document the surgical technique used for en bloc excision of a chordoma arising in the midcervical spine. SUMMARY OF BACKGROUND DATA: Malignant tumors arising in long bones are excised en bloc. The authors recently designed a technique for en bloc resection of malignant tumors in the thoracolumbar spine using the T-saw. However, this technique is difficult in tumors of the cervical spine, and there are no previous reports of successful en bloc resection of such tumors. methods: Using an anterior approach, the ipsilateral vertebral artery was ligated. This was followed by sharply cutting the pedicle of the cervical vertebra with a specially designed T-saw. RESULTS: En bloc excision of chordomas in the cervical spine was achieved using the T-saw. CONCLUSION: Although the surgical margin was intralesional in a small area, the technique used in this case study indicates that en bloc excision of such tumors can be used with a safety margin even in the cervical spine.- - - - - - - - - - ranking = 0.5keywords = chordoma (Clic here for more details about this article) |
5/138. Fine-needle aspiration biopsy of metastatic chordoma: case report and review of the literature.chordoma is a distinct malignant neoplasm arising from the remnants of the notochord and occurring mostly in the fifth or sixth decade of life, and occupying most frequently the sacral area (Bibbo, Comprehensive Cytopathology 1997; p 534). Metastases of the neoplasm may occur in 10-40% of cases (Jenkins et al., Clin. Radiol. 1995;50:416-417). Because of its rarity, the diagnosis of chordoma may be difficult to render, especially on fine-needle aspiration biopsy (FNAB). However, a clear-cut distinction of chordoma from other neoplasms is of utmost importance, since the prognosis and treatment of the patient will depend on the final diagnosis. This distinction in the case of metastases can be made easily, where correlation of previous histology has been done and/or ancillary studies have been performed. Diagn.

6/138. MR findings of desmoplastic fibroma of the spine. A case report.We report on the MR imaging findings in a case of spinal desmoplastic fibroma (DF). DF of the bone is a rare, locally aggressive tumor. It is commonly located in long bones, pelvis or mandible. DF involving the spine is extremely rare and difficult to distinguish from other bony lesions such as giant cell tumor, chordoma and fibrous dysplasia of the spine. This case of DF of the spine showed MR findings similar to those of DF arising in the metaphysis of a long bone.- - - - - - - - - - ranking = 0.16666666666667keywords = chordoma (Clic here for more details about this article) |
7/138. Gluteus maximus adipomuscular turnover or sliding flap in the surgical treatment of extensive sacral chordomas.Two cases with extensive posterior peritoneal defects after high sacral amputation for sacral chordoma are presented. An adipomuscular flap as a modification of the conventional gluteus maximus muscle flap was designed to obliterate an extensive residual posterior peritoneal dead space. The deep adipose tissue beneath the superficial fascia left on the gluteus maximus muscle was effectively used to provide more volume to the flap. The adipomuscular flap was turned over into the posterior peritoneal defect in the first case, and the flap was slid into the cavity in the other case. The adipomuscular flap eventually enabled the successful reconstruction of the posterior peritoneal defect, and the volume of the flap was well maintained behind the rectum, according to the postoperative magnetic resonance imaging findings in both cases.- - - - - - - - - - ranking = 0.83333333333333keywords = chordoma (Clic here for more details about this article) |
8/138. Intradural cervical chordoma. Case report.We describe a rare case of an intradural spinal chordoma. Only two cases have been previously reported and it is the second case diagnosed with MRI. A 65-year-old man presented with progressive disturbance of gait and weakness in the lower extremities. MRI revealed a intradural C6-C7 isointense mass, on T1- and T2-weighted images. The lesion enhanced after injection of gadolinium. The lesion was totally removed without difficulty by a C6-D1 laminectomy. Microscopic examination of the tumor revealed a chordoma. This is the third case in the literature of an intradural spinal chordoma. The appearance of this tumor with MRI may be similar to the chordomas of other locations.- - - - - - - - - - ranking = 1.3333333333333keywords = chordoma (Clic here for more details about this article) |

10/138. Cutaneous metastasis of chordoma.BACKGROUND: Chordomas are rare neoplasms that arise from the notochord remnant. They develop in the sacrococcygeal (50%) or cervical (15%) region and are generally regarded as a locally aggressive tumor with a slow progressive growth rate and a metastatic incidence ranging from 3 to 48%. skin involvement by chordoma is rare, but can occur by direct extension, by local recurrence and by metastases. OBJECTIVE: To illustrate by a case report the clinical presentation and management of this disease. methods: We present a case of sacral chordoma with metastases over a 10-year period to the lungs, the soft tissue of the chest wall, the triceps tendon, and distant cutaneous metastases to the back and the nose. RESULTS: The cutaneous metastases were treated by excision. CONCLUSION: chordoma is a slow growing tumor of the notochord remnant that may metastasize to the skin. physicians and pathologists should be aware of this entity.- - - - - - - - - - ranking = 1keywords = chordoma (Clic here for more details about this article) |
