What procedure and approach is done for a intradural spinal cord tumor?
Hemilaminectomy is a viable approach for the resection of intradural spinal tumors, with similar rates of post-operative complications to laminectomy when using an open surgical approach.
What is intramedullary spine surgery?
In cases of intramedullary spinal cord tumors, early diagnosis and early surgery, before the paralysis becomes severe, are important to obtain good functional outcomes. Surgery for intramedullary spinal cord tumors should aim at complete removal of ependymomas, low-grade astrocytomas and hemangioblastomas.
What is intradural intramedullary?
Intradural tumors are most likely to be found in the thoracic region, followed by the cervical and then lumbar spine. Gliomas make up 80% of all intramedullary tumors. The gliomas are further subdivided into astrocytomas (60 to 70%) and ependymomas (30 to 40%).
How do they remove tumors from spine?
Most symptomatic spinal cord tumors require surgical removal which can typically be performed with small incisions on the back or neck and little bony disruption. Depending on the type of tumor, further treatment may be indicated, including radiation or chemotherapy.
What are intramedullary spinal cord tumors?
Intramedullary spinal cord tumors (IMSCTs), like the one depicted in the image below, refer to a subgroup of intradural spinal tumors that arise from cells within the spinal cord, as opposed to adjacent structures such as the nerve roots or meninges.
What is an intramedullary tumor?
Intramedullary tumors are growths that develop in the supporting (glial) cells within the spinal cord. A spinal tumor is a growth that develops within your spinal canal or within the bones of your spine.
What does intramedullary tumor mean?
What is a intramedullary mass?
Intramedullary masses of the spinal cord are located inside the substance of the cord and are less commonly encountered than masses in the other two compartments of the spine (intradural-extramedullary and extradural). Intramedullary masses usually expand the spinal cord parenchyma rather than displace it.
How long do spinal tumors take to grow?
Primary tumors often progress slowly over weeks to years. Tumors in the spinal cord usually cause symptoms, sometimes over large portions of the body. Tumors outside the spinal cord may grow for a long time before causing nerve damage.
How is surgery used to treat intramedullary tumors?
Intramedullary tumor surgery involves opening the back of spinal cord, which almost always involves some degree of impairment of the nerves that subserve sensation or balance. While this is an unfortunate side-effect of surgery, most find it preferable to the risks associated with letting a tumor grow untreated.
Are there any side effects of intramedullary tumor surgery?
There are some common side effects that you should consider before you schedule an operation. Intramedullary tumor surgery involves opening the back of spinal cord, which almost always involves some degree of impairment of the nerves that subserve sensation or balance.
What happens if you have an intradural spinal cord tumor?
Intradural spinal cord tumors are uncommon lesions and fortunately affect only a minority of the population. However, when lesions grow, they result in compression of the spinal cord, which can cause limb dysfunction, cause motor and sensation loss, and, possibly, lead to death.
Can a schwannoma be an extradural or intradural tumor?
Most schwannomas are purely intradural but 15% have an extradural component, being either solely extradural or both intra- and extradural. These tumors originate from the dorsal sensory nerve root. 3 Typically, these lesions are well encapsulated and rarely include a cystic portion.
