Syringomyelia is a medical condition characterized by the formation of a fluid-filled cyst, or syrinx, within the spinal cord. This cyst can expand and damage the spinal cord, leading to various neurological symptoms. Common signs include pain, weakness, and stiffness in the back, shoulders, and limbs, as well as potential loss of sensation. The condition is often associated with Chiari malformation, where brain tissue extends into the spinal canal. Diagnosis typically involves imaging techniques like MRI to visualize the syrinx. Treatment options may include monitoring, medication, or surgery, depending on the severity of symptoms and the size of the syrinx.
