ependymomas are glial tumors originate from ependymal cells lining the ventricles and the central canal of the spinal cord. two thirds of ependymomas arise in the infratentorial or intraventriclesandone-third aredetected in supratentorial area. however supratentorial “cortical” ependymomas are veryuncommon. ependymomas are usually infratentorial, intraventricular tumor, including 2–9% of all ce...

BACKGROUND In the treatment of spinal cord tumors, complete tumor resection with complete reconstruction of the spine represents the ideal goal. However, for the treatment of heavily calcified spinal meningioma, en-bloc resection of the tumor together with the involved dura at the tumor base through laminectomy is quite difficult. Conventional laminectomy is not wide enough to allow full exposu...

STUDY DESIGN To analyze the expression profile of tumor endothelial marker 7 (TEM7) in the spinal cord and dorsal root ganglion (DRG). PURPOSE To investigate the expression profile of TEM7 in the spinal cord and DRG of adult and developing rats. OVERVIEW OF LITERATURE Tumor endothelial marker 7 (TEM7) is a putative transmembrane protein that is highly expressed in the tumor endothelium and ...

A retrospective analysis was performed on forty cases of spinal cord meningiomas, operated on at Dr. Shariati Hospital from 1976 to 1990. Age and sex distribution, clinical presentation and tumor location were comparable to those reported by others. In males the tumors were distributed evenly in cervical and dorsal areas and were often anterior to the cord. This finding makes a different s...

In the article presented, authors discuss problem of providing high-quality medical care to older patients with cancer. The work focuses on examining patient based a comprehensive geriatric assessment (CGA), including urgent situations related malignant neoplasm. protocol provides an overview hypercalcemia, tumor disintegration syndrome, spinal cord compression, neutropenia. issue educational n...

UNLABELLED Primary spinal involvement in hematological diseases is rare. PURPOSE The purpose of this article is studying diagnostic and treatment strategies in patients with spinal cord primary hematologic tumors causing spinal cord compression syndrome. PATIENTS AND METHODS We report two cases with spinal cord primary hematologic tumors causing spinal cord compression syndrome. One patient...

compound action potential (cap) of spinal cord represents valuable properties of neural fibers including excitability, rate of myelination and membrane integrity. these properties are measured using amplitude, latency and area under curve of caps recorded from spinal cord. here, the isolated spinal cord was set in a double sucrose gap (dsg) chamber and its response to intracellular stimulation ...

Intramedullary spinal cord tumors, and more specifically ependymomas, are rare and can be a source of significantmorbidity for the patient. Resection of large spinal cord ependymomas may be associated with risks because of the extent of the manipulation of spinal cord parenchyma required to remove the tumor. Furthermore, large tumors often partially invade or adhere to the spinal cord, making t...

The diagnosis, localization, and characterization of spinal cord tumors can be difficult even in this modern era of computed tomography (CT). Although magnetic resonance imaging offers the potential for accurate spinal cord imaging, at present myelography and CT with intravenous or intrathecal contrast material are the mainstays in the diagnosis and localization of spinal cord tumors. The preop...
