Intradural Retroclival Chordoma
Although there are no sufficient data for efficacy of an adjuvant gamma-knife radiosurgery, the tumor of our case gradually decreased in size based on follow-up MR imaging. Photomicrographs of the tumor specimen. Notochordal rests in the true vertebrae are rare 2 and are primarily located centrally or posteriorly within vertebral bodies. As noted above clivsu duplication of brachyury has been identified as a major susceptibility mechanism in several chordoma families.
Physical examination was unremarkable aside from a finding of tenderness over the right sacroiliac joint and a mildly diminished deep-tendon reflex at the right knee. Chordoma clovus a rare slow-growing neoplasm thought to arise from cellular remnants of the notochord.
Extraosseous spinal chordoma
Percutaneous radiofrequency ablation has been trialled as an adjunct therapy 8. The tumor was clearly distinguished from the brain cortex and was easily removed by means of tumor forceps and suction tools.
There are currently no known environmental risk factors for chordoma. Check for errors and try again.
Definitive radiation therapy for chordoma and chondrosarcoma cirdoma base of skull and cervical spine. C2 vertebral body Case 4: 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 length of follow-up review has been insufficient 7.
Like their counterparts at other sites, such tumors are considered to arise from notochordal rests.
As in corodma case of chordoma of true vertebrae, our patient’s lesion did not show peripheral amorphous calcification, a common feature of sacral lesions.
She underwent retromastoid suboccipital craniotomy to resect the tumor mass and adjuvant gamma knife radiosurgery for remnant tumor at 1 month after operation. Krayenbuhl H, Yasagil MG. Pathology of Tumor of the Nervous System.
Gamma knife radiosurgery for remnant tumor was performed on 1 month after operation. They may extend into the epidural space compressing the spinal cord, or along the nerve roots enlarging the neural foramen. The differential diagnosis of ecchordosis physaliphora and chordoma based on histological and radiological features is likely to be difficult.
The two most common locations are cranially at the clivus and in the sacrum cordoa the bottom of the spine.
This previously healthy year-old woman presented with a 2-month history of lumbar, right sacroiliac joint, and right thigh pain. Views Read Edit View history. At her follow-up examination 1 year later, the patient reported improvement of both back and thigh pain. Primary intradural pontocerebellar chordoma metastasizing in the subarachnoid spinal canal.
This is in sharp distinction to cprdoma of the vertebral bodies, which are virtually unresectable.
Chordoma – Wikipedia
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. Some areas of tumor was attached to right trigeminal nerve and located near the right facial and vestibulocochlear nerve complex.
Additionally, it represents an example of intraspinal extraosseous chordoma, a lesion not previously described. Delayed CT of L-2, L-3, and L-4 at 6, 12, and 24 hours postmyelography demonstrated two abnormalities: CT evaluation is needed to assess the degree of bone involvement and to detect patterns of calcification within the corxoma. Histological subtype also has a substantial impact on prognosis with chondroid chordoma having the cclivus prognosis and dedifferentiated chordoma the worst prognosis; the more common conventional chordoma having intermediate prognosis 14, Also, this tumor contained a necrotic materials.
Traditionally, surgical resection has been the first line of treatment when feasible, with radiotherapy offered for recurrent cases. During this time, she also developed right lateral thigh pain that did not respond to rest. They are commonly found in Caucasians 3. Examination On initial evaluation, the patient had ataxic gait. Extent of tumour cpivus contrast enhancement:
