What is hydromyelia?

Hydromyelia is an abnormal widening within the central canal, i beg your pardon is usually a very tiny pathway that runs v the center of the spinal cord. This create a cavity, called a syrinx, whereby cerebrospinal liquid (CSF) deserve to accumulate and also put press on the spinal cord. End time, this can damages nerves in the spinal cord.

It has tendency to mainly take place in infants and also children, but there is a comparable condition dubbed syringomyelia that tends to occur mainly in adults. Syringomyelia requires the development of a cyst in the spinal cord that damages this framework of the body as it grows with fluid accumulation. This additionally can cause damage come the nerves in the spinal cord.


Mild hydromyelia doesn’t always cause symptoms. However, together it progresses, it have the right to cause:

loss of feeling in the hands and armspain in neck and arms muscle weakness in the hand, arms, and shouldersleg ache or stiffness

Without treatment, the weakness and stiffness usually become worse and also can eventually make motion difficult.


Doctors no sure about the exact reason of hydromyelia. However, it’s believed to most most likely be related to a blockage or disruption in the circulation of CSF. This isn’t good for your central nervous system, as suitable CSF flow and also associated pressure are necessary to defend the brain and spinal cord. Injuries, basic conditions, and details problems during brain and spinal cord advance in the womb can all cause problems with the circulation of CSF.

There’s likewise a strong link between hydromyelia and Chiari malformations. These are a form of bear defect the affects brain structure. They often reason the cerebellum — the area in the back of the mind that controls movement — and sometimes also the brainstem to relocate downward and also crowd right into the room reserved because that the spinal cord. This block the circulation of CSF.

Other conditions that are linked to hydromyelia include:

spinal cord tumorstethered spinal cord, which refers to tissue attachments involving the lowest an ar of the spinal cord, that protect against it from relocating in the spinal canal favor it should

This uses powerful magnets and also radiofrequency pulses come create an extremely detailed pictures, and also there is no radiation exposure through MRI scans. This imaging test will permit the medical professional to determine tumors or other abnormalities in the brain and spinal cord regions.


Some cases of asymptomatic hydromyelia may be closely monitored without treatment. That possible, but rare, because that some situations of hydromyelia to resolve without treatment. However, if over there are significant symptoms the don’t improve or also worsen, her child might need surgical procedure to exactly the flow of CSF.

Types of surgical treatment include:

Third ventriculostomy. A feet is developed in the bottom the the 3rd ventricle the your brain to draw away CSF flow.
