Syringomyelia is a generic term referring to a disorder in which a cyst or cavity forms within the spinal cord. Often, syringomyelia is used as a generic term before an etiology is determined. [ 3 ] This cyst, called a syrinx , can expand and elongate over time, destroying the spinal cord.
A syrinx can also develop in patients who have a spinal cord tumor, scarring due to previous spinal trauma, or no known predisposing factors. About 30% of people with a spinal cord tumor eventually develop a syrinx. Syringomyelia is a paramedian, usually irregular, longitudinal cavity.
About 10% of ependymomas are benign myxopapillary ependymoma (MPE). [7] MPE is a localized and slow-growing low-grade tumor, which originates almost exclusively from the lumbosacral nervous tissue of young patients. [7] On the other hand, it is the most common tumor of the lumbosacral canal comprising about 90% of all tumoral lesions in this ...
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 ...

Neurofibromatosis type II (also known as MISME syndrome – multiple inherited schwannomas, meningiomas, and ependymomas) is a genetic condition that may be inherited or may arise spontaneously, and causes benign tumors of the brain, spinal cord, and peripheral nerves. The types of tumors frequently associated with NF2 include vestibular ...
Meningococcal myelitis (or meningomyelitis): lesions occurring in the region of meninges and the spinal cord; Osteomyelitis of the vertebral bone surrounding the spinal cord (that is, vertebral osteomyelitis) is a separate condition, although some infections (for example, Staphylococcus aureus infection) can
A nervous system tumor is a tumor that arises within the nervous system, either the central nervous system (CNS) or the peripheral nervous system (PNS). [1] [2] Nervous system primary tumors include various types of brain tumor and spinal tumors, such as gliomas, and meningiomas (of the CNS), and schwannomas (of the PNS) and can be either benign or malignant.
