Intramedullary Tumors. Intramedullary tumors are masses of tissue that form as a result of abnormal cell growth within the spinal cord. These types of tumors can appear anywhere along the spinal cord but are most often found in the cervical area, where more neural tissue is present.

Intramedullary tumors of the spinal cord are rare and account for 2% to 8.5% of all central nervous system tumors. In adults Intradural tumors are located within the dura mater.

Intramedullary tumors are masses of tissue that form as a result of abnormal cell growth within the spinal cord. These types of tumors can appear anywhere along the spinal cord but are most often found in the cervical area, where more neural tissue is present. Primary intra-axial tumors are usually derived from neuroepithelial tissue, especially glial cells. This often leads to a classic intramedullary mass differential diagnosis of ependymoma or astrocytoma, which together constitute up to 70% of spinal cord tumors.

The most common are those originating from the Spinal Cord's supporting cells ("glia") and therefore lie within the substance of the Spinal Cord itself. For intramedullary spinal cord ependymomas, surgical resection is the mainstay of treatment since the risk of local and intracranial recurrence is extremely low. 40,49,54,56 However, in intramedullary spinal cord astrocytomas, resection can be difficult as distinct tumor-cord interfaces may not exist; the higher grades (WHO grades 3 and 4) tend to exhibit a high rate of both local and distant leads the way.

These types of tumors can appear anywhere along the spinal cord but are most often found in the cervical area, where more neural tissue is present. Primary intra-axial tumors are usually derived from neuroepithelial tissue, especially glial cells. This often leads to a classic intramedullary mass differential diagnosis of ependymoma or astrocytoma, which together constitute up to 70% of spinal cord tumors. The most common presenting symptoms for intramedullary tumors are sensory deficits, motor weakness, gait ataxia, and pain.

Th ey comprise about - of all spinal tumors. They are distinguished from intramedullary tumors by their extra-axial location. First recorded resec- Paul C. McCormick, M.D., MPH Columbia University College of Physicians and Surgeons, New York, New York Abstract: Ependymomas are the most commonly occurring Summary: A case of primary malignant melanoma of the conus medullaris depicted at MR imaging is presented. Tumoral histoimmunologic analysis revealed features of malignant melanoma. Because findings for primary melanoma outside the spinal cord were negative, the diagnosis of primary intramedullary malignant melanoma was established. This rare tumor should be suspected when T1-weighted images A T10 to L2 spinal cord tumor exploration and biopsy was performed with intraoperative neurophysiological monitoring (IONM) on a 75-year-old male diagnosed with an intradural intramedullary appearing spinal cord lesion with no other lesions in the central nervous system, chest, abdomen or pelvis. Intramedullary schwannomas are infrequent intramedullary tumors, but approximately 50 cases have been reported in the literature.

One hundred fifty-eight chemotherapy and 183 radiation therapy articles for intramedullary spinal cord tumors were reviewed.

Metastases are being recognized with increasing frequency, primarily because of improvements in imaging modalities. Intradural Intramedullary Tumors: Epidemiology account for 20-30% of all intradural tumors in adults and 50% in children; typically present with symptoms related to: local or radicular pain; motor deficits (65%) sensory deficits (60%) sphincter dysfunction (38%) often initial symptom; Ependymoma. incidence OBJECTIVE: We sought to study the application of precise intraoperative localization of small intramedullary spinal cord tumors.
