Do you have a fluid-filled cyst in your spine? Let's learn about Syringomyelia with Nirogi Lanka

Do you sometimes experience back pain, numbness in your arms, or a persistent difficulty while walking? While many people dismiss these as minor inconveniences, they could be subtle warning signs of an underlying condition that requires medical attention. Today, at Nirogi Lanka, we are shedding light on a rare but serious spinal cord condition you should be aware of: Syringomyelia.

What is Syringomyelia?

Simply put, syringomyelia is the development of a fluid-filled cyst—known as a syrinx—within your spinal cord. Think of your spinal cord as the primary messaging highway that carries vital signals between your brain and the rest of your body. Over time, this syrinx can expand and lengthen, placing pressure on the spinal cord and potentially damaging the delicate nerve fibers that transmit those essential messages.

What is this fluid?

The fluid inside this cyst is cerebrospinal fluid (CSF). Under normal conditions, CSF cushions your brain and spinal cord, acting much like a shock absorber. It flows through cavities in your brain called ventricles and travels down a narrow channel running through the center of your spinal cord, known as the central canal.

If you have syringomyelia, CSF accumulates within the spinal cord tissue, causing the central canal to widen and form a syrinx. This usually happens when the normal flow of CSF around the spinal cord or brainstem is obstructed. If this syrinx puts pressure on your brainstem, the condition is referred to as syringobulbia. Syringomyelia most commonly affects the upper sections of the spine, specifically the cervical (neck) and thoracic (chest) regions.

Who is affected, and how common is it?

Syringomyelia is most frequently diagnosed in adults between the ages of 20 and 50. While it can occur in children and older adults, it remains a very rare condition, affecting approximately 8 out of every 100,000 people. It is estimated to be the underlying cause in about 5% of cases involving paraplegia.

What are the symptoms of Syringomyelia?

Symptoms typically develop slowly over several years and may gradually worsen. Some individuals may have a small syrinx and remain asymptomatic for a long time. Symptoms vary depending on the location, size, and length of the syrinx. You may experience symptoms on one or both sides of your body, ranging from very mild to severe.

Common symptoms include:

• Headaches.
• Pain radiating through your arms, neck, mid-back, or legs (radiculopathy).
• Progressive weakness and muscle wasting (atrophy) in the arms or legs.
• Muscle spasms or tightness in the back, shoulders, neck, arms, or legs.
• Loss of sensitivity to pain or temperature, particularly in the hands.
• Numbness or a tingling sensation in your limbs.
• Balance issues and difficulty walking.
• Loss of bowel or bladder control.
• Sexual dysfunction.

In children, additional symptoms may include:

• Scoliosis (curvature of the spine).
• Toe walking.

Most importantly, if you or your child are experiencing these symptoms, please consult a medical professional immediately.

Why does Syringomyelia occur? What are the causes?

While the exact mechanism for the formation of every syrinx is not fully understood, the prevailing scientific consensus points to an obstruction or disruption in the flow of cerebrospinal fluid (CSF) as the primary cause. Syringomyelia is generally categorized into two types: congenital (present at birth) and acquired (developing later in life).

Congenital Causes

Many cases of syringomyelia are associated with Chiari Malformation Type 1. This occurs when the lower part of the cerebellum (the back of the brain) extends into the foramen magnum—the opening at the base of your skull. Because this is the path the spinal cord normally takes, this structural abnormality disrupts the healthy flow of CSF. While Chiari malformation is congenital, many people remain asymptomatic until early adulthood or later.

Other congenital causes include:

• Myelomeningocele: Also known as open spina bifida, this is a birth defect where the spinal cord and spinal canal fail to close properly during development, classified as a neural tube defect (NTD).
• Tethered Cord Syndrome: This is a rare neurological disorder where the spinal cord becomes attached (tethered) to the surrounding tissues of the spine, often associated with spina bifida and scoliosis.

Acquired Causes

Causes of syringomyelia that develop later in life include:

• Spinal Cord Injuries: This condition is sometimes called post-traumatic syringomyelia. It can develop months or even years after the initial injury. It is frequently caused by scar tissue that disrupts the normal flow of cerebrospinal fluid (CSF).
• Spinal Cord Tumors: Growths such as hemangioblastomas and ependymomas can obstruct CSF pathways, leading to the development of a syrinx.
• Arachnoiditis: The arachnoid is one of the protective membranes surrounding your spinal cord. Inflammation of this membrane can lead to syringomyelia. Underlying causes may include conditions like sarcoidosis, transverse myelitis, and multiple sclerosis (MS).
• Meningitis: This is an infection of the protective membranes (meninges) surrounding your brain and spinal cord, which can also result in syringomyelia.

In some cases, the cause remains unknown; this is referred to as idiopathic syringomyelia.

How is this condition diagnosed? (Diagnosis)

To determine if you have syringomyelia, your doctor will begin by reviewing your medical history and performing a physical exam, with a special focus on your neurological function. You may be referred to a neurologist—a specialist in brain and nervous system disorders.

Next, your doctor will likely order imaging tests of your spine or brain. Occasionally, syringomyelia is discovered incidentally while performing scans for other conditions.

What tests are used to diagnose this?

If your doctor suspects syringomyelia, they may recommend one or more of the following tests:

• MRI (Magnetic Resonance Imaging) Scan: The MRI is the gold standard for diagnosing syringomyelia. It uses powerful magnets and computer technology to create detailed images of your internal structures. This test allows your doctor to identify a syrinx, a tumor, or other abnormalities, clearly showing the location, size, and extent of the syrinx.
• Dynamic MRI: This specialized MRI captures the movement of CSF around your spinal cord and within the syrinx. You may need to receive a contrast agent via an IV to ensure the images are as clear as possible.
• Myelogram with CT Scan: If you are unable to undergo an MRI, a CT scan with a myelogram is often the next choice. A myelogram involves injecting a special contrast dye, followed by a computed tomography (CT) scan to identify issues within the spinal canal.

What are the treatments for Syringomyelia?

Treatment for syringomyelia depends on the severity of your symptoms and how quickly they are progressing.

If you are asymptomatic, doctors typically do not treat syringomyelia directly. However, they will recommend regular monitoring by a neurologist or neurosurgeon to keep an eye on the syrinx, as symptoms can emerge or worsen over time. This monitoring usually includes periodic MRI scans and neurological check-ups.

For patients experiencing symptoms, the goals of treatment at Nirogi Lanka are to:

• Treat the underlying cause of the syrinx, whenever possible.
• Manage your symptoms effectively.
• Restore the normal flow of cerebrospinal fluid (CSF) to prevent further spinal cord damage.

Surgery is typically required to address the underlying cause and prevent further damage. Common management approaches for symptoms include:

• Pain management medications.
• Physical therapy and rehabilitation.
• Lifestyle modifications, particularly avoiding strenuous activities that put stress on your back (such as heavy lifting or jumping).

What types of surgeries are performed for Syringomyelia?

If your condition is causing symptoms or the syrinx is enlarging, your medical team will likely recommend surgery. There are two primary approaches: restoring normal CSF flow around the spinal cord or draining the syrinx directly. The specific surgical approach will depend on the root cause of your condition.

Surgical interventions include:

• Treating Chiari Malformation: The primary goal of this surgery is to create more space at the base of your skull and the upper neck. By doing this, we relieve pressure on your brain and spinal cord, allowing your cerebrospinal fluid (CSF) to flow naturally again. The most common procedure is Posterior Fossa Decompression. During this surgery, your neurosurgeon removes small sections of bone from the back of your skull to provide the necessary room. Following this, the fluid within the syrinx can drain, often causing it to shrink or disappear entirely. Even if the syrinx remains or only partially shrinks, you may still experience significant improvement in your symptoms.
• Treating or Preventing Post-traumatic Syringomyelia: When syringomyelia is caused by an injury, the main focus is to prevent a syrinx from forming or to stop an existing one from growing. This procedure, known as Expansive Duraplasty, involves removing scar tissue around your spinal cord and occasionally using a patch to enlarge the protective membrane (Dura Mater). By creating space and clearing obstructions, we restore the healthy flow of your CSF.
• Removing Obstructions: Surgery can successfully restore CSF flow by removing obstructions such as scar tissue, bone fragments in the spinal canal, or tumors. If a tumor is the cause of your syringomyelia, removing it often resolves the syrinx. In some cases, your doctor may also recommend radiation therapy to help shrink a tumor.
• Draining the Syrinx: If there is no clear cause for your syrinx, or if it is expanding, your doctor may suggest draining it. Your neurosurgeon can place a stent or a shunt. A stent is a small tube that allows fluid to flow from the inside of the spinal cord to the surrounding space. A shunt consists of a flexible tube and a valve that diverts the syrinx fluid to another part of your body, usually your abdomen or chest. Both methods help prevent your symptoms from worsening by reducing the fluid pressure.

After your surgery, your doctor will use MRI scans to monitor whether the syrinx has stabilized or decreased in size.

For many, surgery provides effective symptom relief and stabilizes the condition. However, please be aware that syringomyelia can recur even after successful treatment, which may necessitate further surgical intervention.

What are the potential surgical complications?

Following surgery for syringomyelia, potential complications may include:

• Cerebrospinal fluid (CSF) leakage.
• Infection.
• Hemorrhage (bleeding).
• Further spinal cord injury.
• Recurrence of the syrinx.

It is vital to have a detailed discussion with your neurosurgeon regarding these risks and their likelihood in relation to your specific procedure.

What is the prognosis for Syringomyelia?

It is important to remember that symptoms, severity, and causes of syringomyelia vary widely. The rate of progression also differs, and some people may remain stable without further worsening. Because of this, it is challenging for doctors to provide a definitive prognosis.

Early surgical intervention generally offers the best results and helps minimize symptoms. While surgical treatment often stabilizes neurological deficits, and some symptoms may improve, many individuals continue to manage some degree of long-term symptoms.

Generally, if your syrinx diameter exceeds 5mm and is accompanied by edema (swelling), the prognosis may be less favorable.

Myelopathy (damage to the spinal cord due to severe compression) is a major complication to watch for. It can eventually lead to paralysis (paraplegia/quadriplegia), recurrent pneumonia, and bladder or bowel dysfunction.

Can Syringomyelia be prevented?

Typically, syringomyelia cannot be prevented. However, early diagnosis and prompt treatment are key to preventing the progression of symptoms.

How can I care for myself with Syringomyelia?

If you are living with syringomyelia, consider these steps to manage your symptoms:

• Avoid activities that may worsen your symptoms. This includes heavy lifting, strenuous exertion, or any high-impact movements that put stress on your spine.
• Consider physical therapy to help manage walking difficulties, muscle weakness, stiffness, and pain.
• If you experience chronic pain due to your condition, discuss available pain management options with your healthcare team at Nirogi Lanka.
• Living with syringomyelia can be emotionally taxing. It is important to seek mental health support from friends, family, or professional counselors. Joining a support group can also help you connect with others, reminding you that you are not alone on this journey.

When should you see your doctor about Syringomyelia?

If you have been diagnosed with Syringomyelia, it is essential to consult your medical team regularly to monitor your symptoms and the status of your syrinx, regardless of whether you have undergone surgery or not.
