1. Butterfly saddle area chordoma not surgery, can live long?

2. Objective. The extracellular microenvironment directly affects metastatic chordoma cell phenotype in vitro.

3. Chordoma is a more common tumor in this location than chondrosarcoma.

4. An extensive sacrococcygeal chordoma is considered a challenge for neurosurgeons.

5. Patient groups like the Chordoma Foundation are one of the forces pushing academics and drug companies to start sharing more data in the hopes of speeding up medical innovation.

6. Objective: To Study the characteristic of chordoma in low field MRI and improve MRI diagnostic level.

7. He created a patient group, the Chordoma Foundation, that helped recruit researchers to work on chordoma and to share data.

8. Chondroid chordoma occurred in a younger age group (mean age 40. 9 years) than classic chordoma (mean age 51. 1 years).

9. The differential diagnosis among chondrosarcoma, chordoma, and chondroid chordoma is important due to their different prognoses.

10. Conclusion: The symptoms of the chondroid chordoma occurred in pharynx and larynx are not specific.

11. Conclusion. Wide or marginal en bloc excision of sacral chordoma and chondrosarcoma is associated with significant improvement in disease-free survival with acceptable perioperative morbidity rate.

12. Objective To investigate the diagnosis and endoscopic surgery of clival chordoma with cerebrospinal fluid rhinorrhea (CSFR) as initial symptom.

13. The speaker, Josh Sommer, left college after being diagnosed with a rare type of brain tumor, called a chordoma, and found "information locked inside labs and not being utilized" to help patients.

14. Aim: To investigate the clinical characteristics and surgical approaches of clival chordoma.

15. Objective To evaluate the value of MRI in the diagnosis of intracranial chordoma and nasopharyngeal carcinoma.

15.

16. Destruction of spheno-occipital bone can be found in roentgenogram. It is difficult to distinguish chondroid chord?oma from chordoma and chondrogenic tumors which occur in this region.

17. Conclusion MRI is an effective method for diagnosis of intracranial chordoma and have the important value for diagnosis and identification.

18. Careful evaluation of the calcifications is necessary to avoid confusion with other lesions such as osteosarcoma, chondroma, osteochondroma, or chordoma.

19. Objective To evaluate the effects of surgical treatment of giant clival chordoma.

20. In 8 cases, including 3 cases with osteoblastomas, 2 cases with chordoma, 1 case with giant cell tumor, 1 case with angioendothelioma, 1 case with malignant neurofibroma.

21. Objective To explore the relation between clinical pathological typing and prognosis of sacrococcygeal chordoma.

22. Objective:To investigate the clinical features and outcome of patients with chondroid chordoma of pharynx and larynx.

23. Pathological types include 13 cases of meningioma, 6 of neurinoma, 1 of chordoma, 1 of choroid plexus papilloma, and 1 of hemangiopericytoma.

24. Conclusion: Based on the MRI signal features, central position and margin, correct diagnosis can be made for most of the basicranial nasopharyngeal carcinoma, chordoma and pituitary adenoma.
