Recurrence, including seeding along the operative tract, is common. Thank you for updating your details. The radiological characteristics of the lesion were misleading as it mimicked an arachnoid cyst or a neurogenic neoplasm.

In four of these families, duplication of the brachyury gene was found to be responsible for causing chordoma. The Journal of Bone and Joint Surgery. Typically the mass projects posteriorly at midline, indenting the pons; this characteristic appearance has been termed the so-called thumb sign.
Cerebrospinal fluid fistula secondary to ecchordosis physaliphora.
Extraosseous spinal chordoma
Surgical Implications The tumor in our patient lent itself to complete surgical removal. The tumor dfl enhanced inhomogeneously after administration of gadolinium-diethylenetriamine pentaacetic acid Gd-DTPA. They may extend into the epidural space compressing the spinal cord, or along the nerve roots enlarging the neural foramen.
Postoperative brain CT demonstrates no definite contrast enhancing mass in right cerebellopontine angle region and no bony destruction.
The signal changes seen were nonspecific, and the tumor did not enhance with gadolinium, which is unusual for a neoplasm. Chordomas can occur at any age but are usually seen in adults years. A developmental lesion related to chordoma is the ecchordosis physaliphora. Their locations included the prepontine region in ten cases, the suprasellar region in two cases and the intrasellar, foramen magnum, tentorium and ponto-cerebellar region in one case, respectively.
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.

Magnetic resonance imaging demonstrated that the tumor located in the retroclival and right crerebellopontine angle, growing into right cavernous sinus and Meckel’s cave and compressing the brainstem from medulla to midbrain Fig. This suggests that some people may be genetically predisposed to develop cordoa.
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. Cordmoa of the intradural tumor showing typical physaliphorous cells in mucinous matrix. Therefore, highly focused de, such as proton therapy and carbon ion therapy are more effective than conventional x-ray radiation. 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.
The prognosis in such cases is poor.
Intradural Retroclival Chordoma
Find articles by Sang Wook Joo. Inparticular, the hearing disturbance was more improved after operation. Find articles by Sun-Il Lee. Such tumors often showed extraosseous extensions that were out of proportion to the degree of osseous involvement and were most often anterior and lateral but ccordoma involve the posterior spinal area.
The proximity of chordomas to vital neurological structures such as the brain stem and nerves limits the dose of radiation that can safely be delivered. Embryological Considerations A developmental lesion related to chordoma is the ecchordosis physaliphora.
Find cordom by Seung Jin Noh. The role of radiosurgery in the management of chordoma and chondrosarcoma of the cranial base. Furthermore, unlike other chordomas, intradural chordomas are amenable to resection. MRI of extensive clival chordoma in year-old male patient, axial view.

A small number of families have been reported in which multiple relatives have been affected by chordoma. Cordoka this location, a male predilection has been reported M: SpineCentral Nervous SystemMusculoskeletal.
