There are currently no known environmental risk factors for chordoma. Some areas of tumor was attached to right trigeminal nerve and located near the right facial and vestibulocochlear nerve complex.

The role of radiosurgery in the management of chordoma and chondrosarcoma of the cranial base. Histologically, they are identical to notochordal tissue. MRI of extensive clival chordoma in year-old male patient, axial view. This page was last edited on 14 Novemberat Support Radiopaedia and see fewer ads. The differential diagnosis for bone tumours is dependent on the age of the patient, with a very different set of differentials for the pediatric patient. Increased T 2 -weighted MR signal relative to cerebrospinal fluid, which was present, has been described in some spinal and cranial chordomas with high mucoid content.

There are three histological variants of chordoma: From Wikipedia, the free encyclopedia. Her magnetic resonance images demonstrated an inhomogeneously contrast-enhanced large tumor growing into right cavernous sinus and Meckel’s cave located totally within intradural retroclival region.

Laminectomy and discectomy with exploration of the epidural process were recommended.

The MIB-1 proliferating cell index may be useful in the histological differential diagnosis of chordomas, which are neoplastic tumors, and ecchordoses, which are not true tumor Crainotomy was made until transverse sinus and part of a sigmoid sinus were exposed.

Chordomas are relatively radioresistant, requiring high doses of radiation to be controlled.

The differential diagnosis of ecchordosis physaliphora and chordoma based on histological and radiological features is likely to be difficult. Find articles by Seung Jin Noh. Chordoma is a rare slow-growing neoplasm thought coreoma arise from cellular remnants of the notochord. For tumor control, conventional radiotherapy needs very high doses of radiation.


Extraosseous spinal chordoma in: Journal of Neurosurgery Volume 75 Issue 6 Year

Related Radiopaedia articles Bone tumours The differential dek for bone tumours is dependent on the age of the patient, with a flivus different set of differentials for the pediatric patient. Typically the mass projects posteriorly at midline, indenting the pons; this characteristic appearance has been termed the so-called thumb sign. The tumor in our patient lent itself to complete surgical removal. They are commonly found in Caucasians 3.

Intradural cerebellar chordoma in a child: The patient complained dizziness, but other symptoms, such as ataxia, right facial numbness without paralysis, right hearing disturbance, were much more improved. Postoperative Course The patient made an uneventful postoperative recovery and was ambulating in a cast xel. In contrast, radiosurgery has the advantage of high dose single-session irradiation and efficacy for small sized tumor mass 7 To be analogous to the intracranial ecchordosis, the designation should be expanded to include extraosseous lesions.

F ratio of 2: Microneurosurgery of CNS Tumor; pp. Retrieved from ” https: Expert Recommendations for the Diagnosis and Treatment of Chordoma is a handbook produced by the Chordoma Foundation, which summarizes recommendations developed by a group of over 40 leading doctors who specialize in caring for chordoma patients.

They most commonly involve cervical particularly C2followed by lumbar, and then the thoracic spine. Intradural chordomas are very rare tumors that should be distinguished from neurinomas and classic chordomas, because of their different biological behaviors.

Radiological investigations included magnetic resonance MR imaging with gadolinium enhancement of the lumbar region and an iopamidol myelogram with computerized tomography CT of the lower four lumbar vertebrae.

Intradural Retroclival Chordoma

Giant-cell tumor of bone. Cerebrospinal fluid fistula secondary to ecchordosis physaliphora. In the United Statesthe annual incidence of chordoma is approximately 1 in one million new patients each year.

Case Report This previously healthy year-old woman presented with a 2-month history clivis lumbar, right sacroiliac joint, and right thigh pain. Chordomas are rare tumors of central nervous system about 0. The MR images showed a low-intensity mass. The patient made an uneventful postoperative recovery and was ambulating in a cast brace. Operation Under the impression of acoustic schwannoma, the patient underwent operation.


Some authors 14 reported that the surgically total excision was goal of treatment because the intradural chordomas had cordomaa growth pattern and sharply circumscribed margins compared with classic chordomas.

Additionally, it represents an example of intraspinal extraosseous chordoma, a lesion not previously described. Fluid and gelatinous mucoid substance associated with recent and old hemorrhage and necrotic areas are found within these tumours. Intradural extraosseous chordoma has clearly different features from those of typical chordoma Histological subtype also has a substantial impact on prognosis with chondroid chordoma having the best prognosis and dedifferentiated chordoma the worst prognosis; the more common conventional chordoma having intermediate prognosis 14, However, if allowed to grow for long periods, it may invade the dura and extend intradurally as well as extradurally 13 The tumor was enhanced inhomogeneously after administration of gadolinium-diethylenetriamine pentaacetic acid Gd-DTPA.

Preoperative MR images presenting the intradural retroclival tumor with growing into right cavernous sinus and Meckel’s cave. Cranial nerve examination revealed no gag reflex, uvula deviation to left side, decreased hearing acuity on ckivus ear, decreased taste on right side of tongue and numbness on right V1, V2 dermatome. The position of the tumor at L-3 and the friability of the tumor tissue resulted in piecemeal removal. It is of interest that the MR image in our case failed to delineate the right-sided disc herniation.

On initial evaluation, the patient had ataxic gait. Cary Tennisthe popular advice columnist for Salon.
