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.
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 fluid-filled lesion forms, known as a syrinx. [1] This can vary in size significantly between patients. [1] Nerve fibres may be compressed where they cross the midline, or in other parts of the spinal cord. [1] Cranial nerves may be affected. [3] Syringobulbia may be associated with syringomyelia, a syrinx limited to the spinal cord. [4]
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 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.
Spinal tumor; Myelomeningocele; Syringomyelia; Hydromyelia. In hydromyelia, a dilation of the central canal of the spinal cord is caused by an increase of cerebrospinal fluid. [7] Syringohydromyelia (i.e., both Syringomyelia and Hydromyelia) [7] Tethered cord; In some cases, the terminal ventricle may cause clinical symptoms due to its expansion.
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]
Tethered spinal cord can be caused by various conditions but the main cause is when tissue attachments limit the movement of the spinal cord in the spinal column which causes abnormal stretching of the cord. The tethered spinal cord syndrome is correlated with having the causes: [9] Spina bifida. Occulta; Mylomeningocele; Meningocele; History ...
