What is an intradural mass?

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.

What is a intradural extramedullary tumor?

Intradural extramedullary tumors arise outside of the spinal cord but inside the dural sheath that surrounds the spinal cord, with the vast majority of these tumors slow-growing and benign. However, like other spinal tumors, complications may arise as the tumor grows and puts pressure on the spinal cord.

What causes intradural extramedullary tumor?

Intradural extramedullary tumors are located inside the dura, but outside of the spinal cord. They might develop from nerve roots or from the inside surface of the dura mater. Meningiomas and nerve sheath tumors make up the majority of intradural extramedullary tumors. Both kinds of tumors are usually benign.

What is the most common intradural extramedullary tumor in children?

Onset usually occurs with chronic nonspecific symptoms and may depend on the intra- or extradural neoplastic location. Meningiomas, schwannomas, and neurofibromas are the most common intradural-extramedullary lesions, while astrocytomas and ependymomas represent the majority of intramedullary tumors.

How do I know if I have had a spinal tumor?

Some common signs of spinal tumors may include: Pain (back and/or neck pain, arm and/or leg pain) Muscle weakness or numbness in the arms or legs. Difficulty walking.

What is the most common type of extramedullary spinal neoplasm?

Meningioma and schwannoma are the two most common intradural extramedullary tumors, and both are associated with neurofibromatosis. Meningiomas are most common in the thoracic spine and show a strong female predilection and a clinical manifestation related to compression of the spinal cord or nerve roots.

Can tumors on the spine be removed?

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.

How do they remove a tumor from your spine?

The optimal treatment for a spinal cord tumor is in-part related to the type and location. However, the great majority are treated with surgical removal usually through a laminectomy and microsurgical resection. The goal of surgery is maximal but safe removal with avoidance of worsening neurological function.

What is Lipomyelomeningocele?

A lipomyelomeningocele (pronounced lipo-my-elo-men-IN-go-seal) is a birth defect that affects a child’s backbone (spine). A lipomyelomeningocele is a fatty mass under the skin on the child’s back. It is usually in the middle of the back. The mass attaches to the spinal cord and may slowly pull on the cord.

Can a tumor be mistaken for a herniated disc?

Tumors of the spinal cord or near the sciatic or femoral plexus can cause neural compression and clinical signs similar to those of disc herniation. Such tumors are usually misdiagnosed as discal herniation and appropriate treatment is delayed.

How long can you live with a spinal tumor?

Survival rates for more common adult brain and spinal cord tumors

Type of Tumor 5-Year Relative Survival Rate
Oligodendroglioma 90% 82%
Anaplastic oligodendroglioma 76% 67%
Ependymoma/anaplastic ependymoma 92% 90%
Meningioma 84% 79%

Which is the best description of extra axial brain tumors?

The category of extra-axial brain tumors includes a large number of varied pathologic tumors grouped by their primarily extraparenchymal involvement, typically involving the meningeal layers of the brain. Extra-axial tumors are responsible for approximately half of all intracranial neoplasms in the USA ( Dolecek et al., 2012 ).

How is an extramedullary mass different from an intradural mass?

An extramedullary mass will push the cord away from it whereas an intramedullary lesion will expand and thin the cord around it (this is known elsewhere as the claw sign). Sometimes one must also consider whether a mass is actually extradural, and again examination of the dura above and below the mass is useful.

Is there a difference between extradural and intradural spinal cord tumors?

Spinal cord tumors can be either extradural or intradural; extradural tumors exist outside of the dura mater, the thin membrane that protects the brain and spinal cord, while intradural tumors exist inside of it. Intradural tumors are usually primary tumors, meaning they develop in a certain location…

Are there any treatment options for intradural extramedullary tumors?

Depending upon when the intradural extramedullary tumor is discovered, there are several treatment options that may be possible. The treatment option recommended by your physician depends on whether or not the tumor is cancerous or noncancerous. Even if noncancerous, the tumor is still dangerous because it can affect you neurologically.
