The central canal of the spinal cord may be widened. [1] 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]
The central canal (also known as spinal foramen or ependymal canal) is the cerebrospinal fluid-filled space that runs through the spinal cord. [1] The central canal lies below and is connected to the ventricular system of the brain , from which it receives cerebrospinal fluid, and shares the same ependymal lining.
Excess cerebrospinal fluid in the central canal of the spinal cord is called hydromyelia. This term refers to increased cerebrospinal fluid that is contained within the ependyma of the central canal. When fluid dissects into the surrounding white matter forming a cystic cavity or syrinx, the term syringomyelia is applied. As these conditions ...
Cerebrospinal fluid fills the syrinx. Pressure differences along the spine cause the fluid to move within the cyst. Physicians believe that it is this continual movement of fluid that results in cyst growth and further damage to the spinal cord. In the case of syringomyelia, the syrinx can expand and elongate over time, destroying the spinal ...

Myelography is a type of radiographic examination that uses a contrast medium (e.g. iodised oil [1]) to detect pathology of the spinal cord, including the location of a spinal cord injury, cysts, and tumors.
Tarlov cysts are most commonly located in the S1 to S4/S5 region of the spinal canal, but can be found along any region of the spine.They usually form on the extradural components of sacrococcygeal nerve roots at the junction of dorsal root ganglion and posterior nerve roots and arise between the endoneurium and perineurium.

Central cord syndrome (CCS) is the most common form of cervical spinal cord injury (SCI). It is characterized by loss of power and sensation in arms and hands. It usually results from trauma which causes damage to the neck, leading to major injury to the central corticospinal tract of the spinal cord. [1]
