Syringohydromyelia is a neurological condition characterized by a combination of Hydromyelia (dilation of the central canal) and Syringomyelia (formation of cerebrospinal fluid-filled cavities within the spinal cord tissue).
Background
In clinical practice, the terms hydromyelia and syringomyelia are often used synonymously or grouped under the umbrella term syringohydromyelia, as an exact morphological distinction can be difficult on imaging.
