What is Intra Dural?

Intradural-Extramedullary tumors grow within the spinal canal but outside of the nerves. These tumors are usually slow-growing and benign, but can cause some pain and weakness.

What is an extramedullary mass?

An intradural extramedullary tumor is a spinal cord tumor that causes spinal cord compression — nerves in and around the spinal cord are compressed as the tumor grows in size. The vast majority of these tumors are benign and treated with surgery.

How can you differentiate between intramedullary and extramedullary spinal lesions Radiology?

Intradural lesions occur within the dural sac and are further classified as either intradural intramedullary or intradural extramedullary lesions. Intramedullary intradural lesions are within the substance of the cord. Extramedullary lesions are located within the dural sac but exterior to the spinal cord.

What is an intradural mass?

A spinal cord tumor, also called an intradural tumor, is a spinal tumor that that begins within the spinal cord or the covering of the spinal cord (dura). A tumor that affects the bones of the spine (vertebrae) is called a vertebral tumor.

Are spinal tumors always cancerous?

Spinal tumors can be benign (non-cancerous) or malignant (cancerous). Primary tumors originate in the spine or spinal cord, and metastatic or secondary tumors result from cancer spreading from another site to the spine.

What are intramedullary lesions?

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 intraspinal lesion?

Abstract. Background: Intraspinal tumors are rare central nervous system neoplasms. The reported clinical features of intraspinal tumors have varied in previous studies. We present here the cases of 184 patients with intraspinal tumors treated surgically in our hospital and a review of the literature.

Does lumbar laminectomy weaken the spine?

A few potential complications of open lumbar laminectomy are: Neural tissue damage. Injury to the spinal cord’s dura, cauda equina syndrome, nerve roots, and the formation of scar tissue may occur causing neural tissue damage in the lumbar spine.
