Syringomyelia, central cord syndrome.
Cerebral spinal fluid circulates within the spinal column and around the brain. In a central cord syndrome, there is selective damage to the gray matter from a lesion in the central area of the cord. In larger lesions, the white matter can also be affected, producing progressive symptoms that can be traced through the deficits in various spinal tracts.
In syringomyelia, there is a cavitation, or syrinx, of the spinal cord from fluid backup, producing central pressure against the surrounding matter. A communicating syrinx is typically filled with CSF, while a non-communicating syrinx can be filled with other fluid.
The most common cause is a Chiari malformation, in which the brain presses down on the spinal cord at the base of the skull. Other causes include spinal cord trauma or kyphoscoliosis or other mechanical causes that restrict the circulation of fluid within the central canal of the spinal cord.
