Views Read Edit View history. The role of radiosurgery in the management of chordoma and chondrosarcoma of the cranial base.
Chordomas, chondromas, and chondrosarcomas. 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.
Extraosseous spinal chordoma
Embryological Considerations A developmental lesion related to chordoma is the ecchordosis physaliphora. This dose may carry a high risk of severe radiation injury to the corroma brain structures 9.
Related Radiopaedia articles Bone tumours The differential diagnosis for clivux tumours is dependent on the age of the patient, with a very different set of differentials for the pediatric patient. In the first consensus guidelines for the diagnosis and treatment of chordoma were published in the Lancet Oncology.
After near total resection of tumor Fig. It can be seen that many are from the pre-MRI era, and many do not provide histological or immuno-cytochemical evidence, raising the possibility that some may not be entirely extraosseous and some may be not actually be chordoma.
They often extend across the intervertebral disk space, involving more than one vertebral segment. In contrast, radiosurgery has the advantage clifus high dose single-session irradiation and efficacy for small sized tumor mass 7 Sitting, especially driving, aggravated the pain, whereas standing and lumbar hyperextension provided some relief.
Histologically, they are identical to notochordal tissue.
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. These foci were micro- rather than macroscopic, were entirely intraosseous, and bore no physical resemblance to ecchordosis physaliphora occurring in the cranial region.

These tumours are often poorly marginated and microscopic distal extension of tumor cells likely explains the frequency of recurrences.

Case Report This previously healthy year-old woman presented with a 2-month history of lumbar, right sacroiliac joint, and right thigh pain.
Laboratory investigations were within normal limits for the patient’s age. Surgical experience and review of the literature. Postoperative course The patient complained dizziness, but other symptoms, such as ataxia, right facial numbness without paralysis, right hearing disturbance, were much more improved.
Cranial nerve examination revealed no gag reflex, uvula deviation to left side, decreased hearing acuity on right ear, decreased taste on right side of tongue and numbness on right V1, V2 dermatome. In a series of spinal chordomas reported by Sundaresan, et al. Including the this case, only 18 previous cases of primary intradural and intradural extraosseous chordoma have been reported Table 1 1468 It lay within the loose areolar tissue of Batson’s plexus and did not involve surrounding structures such as the common dural sac, nerve roots, vertebral body, or pedicle or ligamentous structures.

Computerized tomography scan at the L-2 interspace demonstrating a focal disc herniation on the right arrow. Atlas of Cranial Base Surgery. Since chordomas arise in bone, they are usually extradural and result in local bone destruction. Operation Under the impression of acoustic schwannoma, the patient underwent operation.
Although there are no sufficient data clivjs efficacy of an adjuvant gamma-knife radiosurgery, the tumor of our case gradually decreased in size based on follow-up MR imaging. Find articles by Sang Wook Joo.
