Syrinx

The term syrinx refers to a fluid-filled cavity that forms within the spinal cord or, occasionally, in the brainstem. When it is located in the spinal cord, it is usually called syringomyelia, and its growth can gradually compress neighboring nerve structures.

How it may present: Depending on its size and location, it may be associated with pain, weakness, sensory changes—especially to temperature and pain—or muscle stiffness, symptoms that tend to progress slowly over time.

Associated causes: It may be related to abnormalities at the junction between the skull and the spine, to previous spinal cord trauma, or to other conditions that affect the flow of the fluid surrounding the central nervous system.

Which specialist evaluates it? The neurosurgeon is the one who assesses these types of findings and their possible impact. If you have neurological symptoms that progress little by little, letting this specialist know is what is recommended.
