Syringomyelia

Syringomyelia (/sᵻˌrɪŋɡəmaɪˈiːliə, -ɡoʊ-/) is a generic term referring to a disorder in which a cyst or cavity forms within the spinal cord. This cyst, called a syrinx, can expand and elongate over time, destroying the spinal cord. The damage may result in pain, paralysis, weakness, and stiffness in the back, shoulders, and extremities. Syringomyelia may also cause a loss of the ability to feel extremes of hot or cold, especially in the hands. There is also a disorder that generally leads to a cape-like pain (extreme pain, pressure, and many other painful symptoms in the area where a cape would be) and temperature sensation along the back and arms. Each patient experiences a different combination of symptoms. These symptoms typically vary depending on the extent and, often more critically, to the location of the syrinx within the spinal cord.
