What is an Extradural mass?
Extradural tumors originate outside the thecal sac and account for 60% of spinal cord neoplasms. The most common site for extradural tumors is the vertebral body. Metastatic disease is the most common source of an extradural neoplasm, outnumbering primary bone tumors and tumors originating in the epidural space.
What is vertebral mass?
A vertebral tumor is a type of spinal tumor affecting the bones or vertebrae of the spine. Spinal tumors that begin within the spinal cord or the covering of the spinal cord (dura) are called spinal cord tumors. Tumors that affect the vertebrae have often spread (metastasized) from cancers in other parts of the body.
What is a chordoma?
Chordomas are tumors that can occur anywhere within the spine or the base of the skull. The two most common locations for chordomas are the lower back (sacral area — approximately one-third to one-half of chordomas) and the base of the skull (approximately one-third of chordomas).
What is the difference between intradural and Extradural?
Extradural lesions are located outside of the surrounding dural sac; they are often related to lesions of the intervertebral disc or the spinal column. Intradural lesions occur within the dural sac and are further classified as either intradural intramedullary or intradural extramedullary lesions.
Can you feel a spinal tumor with your hand?
A loss of sensation can occur in the arms and legs, and especially in the feet, hands, fingers and toes, as a result of the nerve damage caused by a spinal tumor. You might also feel coolness in these areas or sudden, sharp pain.
What does a tumor in the spine feel like?
Spinal tumor pain may feel like an achiness or discomfort deep within the back, rather than feeling painful on the surface or skin. Sharp or shock-like pain.
How serious is a tumor on the spine?
Spinal tumors or growths of any kind can lead to pain, neurological problems and sometimes paralysis. A spinal tumor can be life-threatening and cause permanent disability. Treatment for a spinal tumor may include surgery, radiation therapy, chemotherapy or other medications.
What kind of tumor is a chordoma?
Chordoma is a slow growing cancer of tissue found inside the spine. Chordoma can happen anywhere along the spine. It is most often found near the tailbone (called a sacral tumor) or where the spine meets the skull (called a clival tumor). Chordoma is also called notochordal sarcoma.
Can you survive chordoma?
Chordomas are malignant and potentially life threatening tumors. Currently the median survival in the United States is about 7 years. The overall survival rates are 68% at 5 years and 40% at 10 years. Complete surgical resection offers the best chance for long-term survival.
Is epidural the same as Extradural?
Extradural hematoma (EDH), also known as an epidural hematoma, is a collection of blood that forms between the inner surface of the skull and outer layer of the dura, which is called the endosteal layer.
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.
What does the term extradural mean in medical terms?
Extradural means ” outside the dura ” the dura being the tough fibrous. layer if tissue which surrounds the brain and spinal cord. The structures immediately outside the dura are the bones (vertebrae ) and discs of the spinal cord.
What are the different types of spinal epidural mass?
The differential diagnosis for a spinal epidural mass includes: epidural metastasis. epidural abscess. herniated nucleus pulposus. epidural haematoma. epidural arteriovenous malformation. epidural angiolipoma. epidural lipomatosis.
Can a dural tail be an extra axial mass?
Classic “hyperostosis” of underlying bone is present in only 5% of cases; typical meningioma may erode bone. On MRI, a “dural tail” suggests a mass in extra-axial but is probably related to reactive changes rather than tumor extension.
Which is the single most common intradural extramedullary neoplasm?
Which of these tumors is the single most common intradural extramedullary neoplasm is controversial.
