This dose dl carry a high risk of severe radiation injury to the normal brain structures 9. Those located in the spheno-occipital region most commonly occur in patients years of age, whereas sacrococcygeal chordomas are typically seen in a slightly older age group vordoma around 50 years This herniation was not evident on the magnetic resonance imaging despite axial sections through this interspace.
Chordomas of the vertebral bodies are rare, but nonetheless, after lymphoproliferative tumours, are the second most common primary malignancy of the spine in adults 2.
This article has been cited by other articles in PMC. The Journal of Bone and Joint Surgery. For this reason, we selected stereotactic radiosurgery for cprdoma tumor in our case.
Chordoma is a rare slow-growing neoplasm thought to edl from cellular remnants of the notochord. They are commonly found in Caucasians 3. The decision whether complete or incomplete surgery should be performed primarily depends on the anatomical location of the tumor and its proximity to vital parts of the central nervous system. They may extend into the epidural space compressing the spinal cord, or along the nerve roots enlarging the neural foramen.
Intradural Retroclival Chordoma
The signal changes seen were nonspecific, and the tumor did not enhance with gadolinium, which is unusual for a neoplasm. Author information Article notes Copyright and License information Disclaimer.
However, if allowed to grow for long periods, it may invade the dura and extend intradurally as well as extradurally 13 Operation Surgery was performed under general anesthesia by one of the authors B. A portion of clicus tumor showing strong uniform keratin reactivity. A soft, friable and grayish mass was seen. Therefore, highly focused radiation such as proton therapy and carbon ion therapy are more effective than cogdoma x-ray radiation.
The radiological appearance of our tumor was not diagnosed either on plain radiography, CT, or Coordoma imaging. Neuropathology and Applied Neurobiology. The disc protrusion at the L-2 interspace was considered clinically significant in that it explained the presence of pain in the right thigh. C2 vertebral body Case 4: Abstract A year-old woman presented with dizziness, ataxia and right hearing difficulty. Intradural retroclival chordoma without bone involvement: The patient was not aware of progressive neurological loss.
Intradural Retroclival Chordoma
Percutaneous radiofrequency ablation has been trialled as an adjunct therapy 8. MRI of extensive clival chordoma in year-old male patient, axial view. True malignant forms of chordomas occasionally have areas of typical chordoma as well as undifferentiated areas, most often fibrosarcoma.
Tumors of Bones and Joints: MRI provides excellent anatomical delineation of adjacent structures and is able to characterize the signal of the lesion usually allowing for a confident preoperative diagnosis. The variety of these components may explain the signal heterogeneity observed on MRI. Typically the mass projects posteriorly at midline, indenting the ddel this characteristic appearance has been termed the so-called thumb sign. Postmyelography computerized tomography scan at the level of the L-3 neural foramen confirming a noncalcified extradural extraosseous mass.
As noted above germline duplication of brachyury has been identified as a major susceptibility mechanism in several chordoma families. Both of these factors raised the possibility of tumor recurrence and seeding. Wikimedia Commons has media related to Chordoma. The patient made an uneventful postoperative recovery and was ambulating in a cast brace.
In contrast to sacrococcygeal tumours, there is no recognised gender difference. However, stereotactic radiosurgery is valuable as an adjuvant or primary treatment for selected patients with chordoma and has potential advantages over standard fractionated irradiation, although the coroma of follow-up review has been insufficient 7.

Traditionally, surgical resection has been cordoja first line of treatment when feasible, with radiotherapy offered for recurrent cases. Preoperative hearing threshold was 90 dB on the right and 45 dB on the left side by brainstem auditory evoked potential BAEPand it was improved to 35 dB on the right and 30 dB on the left side by BAEP studied on 11th postoperative day. Laminectomy and discectomy with exploration of the epidural process were recommended.
This previously healthy year-old woman presented with a 2-month history of lumbar, right sacroiliac joint, and right thigh pain. Find articles by Sun-Il Lee. Rest of operation was uneventful.
SpineCentral Nervous SystemMusculoskeletal. Benign bone erosion with sclerotic borders can cordoja seen arrowindicating a long-standing erosive, rather than destructive, process. Surgical experience and review of the literature. Intradural chordomas are extremely rare and, although they resemble classic chordomas in terms of both their notochordal origin and microscopic features, they are clinicopathologically distinct. Corvoma, chondromas, and chondrosarcomas.
