Preferred Label : hydromyelia;
Definition : Hydromyelia refers to an abnormal widening of the central canal of the spinal cord
that creates a cavity in which cerebrospinal fluid (commonly known as spinal fluid)
can accumulate. As spinal fluid builds up, it may put abnormal pressure on the spinal
cord and damage nerve cells and their connections. Hydromyelia is sometimes used interchangeably
with syringomyelia, the name for a condition that also involves cavitation in the
spinal cord. In hydromyelia, the cavity that forms is connected to the fourth ventricle
in the brain, and is almost always associated with infants and children who have hydrocephalus
or birth defects such as Chiari Malformation II and Dandy-Walker Malformation. Syringomyelia,
however, features a closed cavity and occurs primarily in adults, the majority of
whom have Chiari Malformation II or have experienced spinal cord trauma. NINDS;
