Most symptoms from spinal tumors occur due to compression of the spinal cord as it plays a primary role in motor and sensory function. [13] The spinal cord is surrounded by three layers known as the spinal meninges. [13] These are the dura mater, arachnoid mater, and pia mater. Spinal cord tumors are classified based on their location within ...
A central nervous system tumor (CNS tumor) is an abnormal growth of cells from the tissues of the brain or spinal cord. [1] CNS tumor is a generic term encompassing over 120 distinct tumor types. [2] Common symptoms of CNS tumors include vomiting, headache, changes in vision, nausea, and seizures. [3]
Meningioma, also known as meningeal tumor, is typically a slow-growing tumor that forms from the meninges, the membranous layers surrounding the brain and spinal cord.

Compression of the spinal cord may result in paralysis, especially if the cause is not detected promptly. [4]
Laminotomies may also be used to treat intraspinal lesions such as spinal tumor or problems with the blood vessels supplying the spinal cord. [4] In any scenario where the inside of the spinal canal must be accessed or there is an increase in pressure in the spinal canal, laminotomy may be used to treat the disorder or alleviate symptoms.
