Hearing that you may have a cyst on your spine can sound alarming. Many patients immediately worry about serious spinal damage, paralysis, or the possibility of needing surgery.

The good news is that most spinal cysts are non-cancerous and treatable. In many cases, they can be managed conservatively without surgery. However, some spinal cysts can compress nerves, cause significant pain, or lead to neurological symptoms that require more advanced treatment.

At Big Apple Spine & Orthopedics in Manhattan, Dr. Grigoriy Arutyunyan regularly evaluates patients with spinal cysts causing back pain, sciatica, numbness, weakness, and mobility problems. Early diagnosis is important because symptoms often worsen gradually over time as the cyst enlarges or places increasing pressure on nearby nerves.

This guide explains what spinal cysts are, the different types that can develop near the vertebrae, common symptoms, how they are diagnosed, and when surgery may become necessary.

What Is a Spinal Cyst?

A spinal cyst is a fluid-filled sac that develops in or around the spine.

These cysts may form:

• Near the vertebrae
• Around spinal joints
• Inside the spinal canal
• Adjacent to nerve roots

Some spinal cysts remain small and never cause symptoms. Others grow large enough to compress nerves or narrow the spinal canal.

The impact of a spinal cyst depends largely on:

• Its size
• Its location
• Whether it compresses nearby nerves or spinal structures

At Big Apple Spine & Orthopedics, Dr. Grigoriy Arutyunyan carefully evaluates whether a spinal cyst is actually responsible for a patient’s symptoms or simply an incidental imaging finding.

Are Spinal Cysts Dangerous?

Most spinal cysts are benign, meaning they are non-cancerous.

However, they can still cause serious symptoms if they:

• Compress nerves
• Narrow the spinal canal
• Affect spinal stability
• Interfere with nerve function

Some cysts remain harmless for years, while others progressively worsen and require treatment.

Common Types of Spinal Cysts

Several types of cysts can occur near the spine.

Synovial Cysts

Synovial cysts are one of the most common spinal cysts.

These cysts develop from the facet joints, which connect the vertebrae and help the spine move.

Facet joints contain lubricating fluid, and degeneration or arthritis may cause this fluid to form a cyst.

Where Synovial Cysts Usually Occur

They are most common in the:

• Lumbar spine (lower back)
  especially at:
• L4-L5

This area experiences significant motion and stress.

Symptoms of Synovial Cysts

Symptoms may include:

• Lower back pain
• Sciatica
• Leg numbness
• Tingling
• Muscle weakness
• Difficulty walking

Symptoms often worsen when standing or walking.

Tarlov Cysts

Tarlov cysts are fluid-filled sacs that form around nerve roots, typically near the base of the spine.

Many Tarlov cysts cause no symptoms, but larger cysts may compress nerves.

Symptoms of Tarlov Cysts

• Lower back pain
• Pelvic pain
• Leg pain
• Numbness
• Bowel or bladder symptoms in severe cases

Arachnoid Cysts

Arachnoid cysts form within the membranes surrounding the spinal cord.

These cysts may compress the spinal cord or nerve roots depending on their size and location.

Symptoms of Arachnoid Cysts

• Back pain
• Weakness
• Numbness
• Coordination problems
• Difficulty walking

Ganglion Cysts

Ganglion cysts resemble synovial cysts and often develop near spinal joints.

They are associated with:

• Degenerative changes
• Joint instability
• Arthritis

What Causes Spinal Cysts?

Several factors may contribute to spinal cyst formation.

Degenerative Arthritis

Spinal wear and tear is one of the most common causes, especially with synovial cysts.

As joints deteriorate, inflammation and excess joint fluid may lead to cyst formation.

Aging

Most spinal cysts occur in older adults due to age-related spinal degeneration.

Spinal Instability

Abnormal movement between vertebrae can contribute to cyst development.

Trauma or Injury

In some cases, prior injury may contribute to cyst formation.

Congenital Factors

Certain cysts may develop due to structural abnormalities present from birth.

Common Symptoms of a Spinal Cyst

Symptoms vary depending on:

• Cyst size
• Location
• Nerve involvement

Some cysts cause no symptoms at all.

Lower Back Pain

One of the most common symptoms is chronic lower back pain.

Pain may:

• Worsen with standing
• Improve while sitting
• Increase with walking

Sciatica

When a cyst compresses a spinal nerve, patients may develop sciatica.

Symptoms include:

• Radiating leg pain
• Burning sensations
• Tingling
• Numbness

Leg Weakness

Nerve compression may affect muscle strength.

Patients may notice:

• Difficulty walking
• Leg instability
• Weakness climbing stairs

Numbness and Tingling

Compressed nerves may cause abnormal sensations in the:

• Legs
• Feet
• Buttocks

Difficulty Standing or Walking

Spinal cysts can contribute to spinal stenosis symptoms, making prolonged standing difficult.

Symptoms That Require Immediate Medical Attention

Seek urgent medical care if symptoms include:

• Loss of bowel or bladder control
• Severe leg weakness
• Rapid neurological decline
• Numbness in the groin area

These symptoms may indicate significant nerve compression.

How Spinal Cysts Are Found

Many spinal cysts are discovered during imaging for back pain or sciatica.

At Big Apple Spine & Orthopedics, diagnosis begins with a comprehensive evaluation.

Physical Examination

Dr. Grigoriy Arutyunyan evaluates:

• Strength
• Reflexes
• Sensation
• Mobility
• Nerve function

MRI Imaging

MRI is the best imaging test for spinal cysts because it provides detailed images of:

• Soft tissues
• Nerves
• Spinal canal structures

MRI can determine:

• Cyst size
• Exact location
• Degree of nerve compression

CT Scans

CT scans may help evaluate:

• Bone structures
• Joint degeneration
• Spinal stability

X-Rays

X-rays do not show cysts directly but may reveal:

• Arthritis
• Degenerative changes
• Spinal alignment issues

Do All Spinal Cysts Need Treatment?

No.

Many spinal cysts do not cause symptoms and may only require monitoring.

Treatment depends on:

• Symptoms
• Nerve compression
• Functional limitations
• Severity of pain

At Big Apple Spine & Orthopedics, Dr. Grigoriy Arutyunyan focuses on treating the patient—not just the MRI findings.

Non-Surgical Treatment Options

Many patients improve with conservative care.

Physical Therapy

Therapy may help:

• Improve spinal stability
• Reduce inflammation
• Improve mobility
• Strengthen supporting muscles

Anti-Inflammatory Medications

Medications may reduce:

• Pain
• Swelling
• Nerve irritation

Epidural Steroid Injections

Injections may temporarily reduce inflammation around compressed nerves.

Some patients experience meaningful symptom relief.

Activity Modification

Patients may need to avoid:

• Heavy lifting
• Prolonged standing
• Repetitive spinal stress

Image-Guided Aspiration

In select cases, cysts may be drained using imaging guidance.

However, recurrence is relatively common.

When Surgery Is Needed

Surgery may become necessary if:

• Severe nerve compression develops
• Weakness progresses
• Pain becomes debilitating
• Conservative treatment fails
• Walking ability declines

At Big Apple Spine & Orthopedics, surgery is typically considered only after appropriate conservative measures have been explored.

Surgical Options for Spinal Cysts

Cyst Removal (Excision)

The cyst is surgically removed to relieve nerve compression.

Decompression Surgery

This procedure creates more space around compressed nerves.

Spinal Fusion

If instability is present, fusion may be recommended along with cyst removal.

Minimally Invasive Spine Surgery

Many spinal cyst procedures can now be performed using minimally invasive techniques.

Benefits may include:

• Smaller incisions
• Reduced muscle damage
• Faster recovery
• Less postoperative pain

Dr. Grigoriy Arutyunyan specializes in minimally invasive spine surgery techniques when appropriate.

Recovery After Surgery

Recovery depends on:

• Procedure type
• Overall health
• Severity of nerve compression

Many patients experience significant relief from:

• Leg pain
• Numbness
• Walking difficulty

Physical therapy may help restore strength and mobility after surgery.

Can Spinal Cysts Come Back?

Some cysts may recur over time, especially if underlying spinal instability or arthritis remains present.

Long-term spine health management is important for reducing recurrence risk.

Preventing Worsening Spine Degeneration

While not all cysts are preventable, maintaining spinal health may reduce progression of degenerative changes.

Stay Physically Active

Movement helps maintain spinal mobility and strength.

Strengthen Core Muscles

Core support reduces spinal stress.

Maintain Healthy Weight

Excess body weight increases spinal pressure.

Practice Proper Posture

Good alignment reduces unnecessary joint stress.

Avoid Smoking

Smoking accelerates spinal degeneration.
