Tarlov Cyst
Tarlov cysts, also known as perineural cysts, are fluid-filled sacs. They develop along the nerve roots of the spine, mostly in the sacral region. These cysts can cause a range of symptoms and significantly impact a person’s quality of life.
While Tarlov cysts are often asymptomatic, they can lead to chronic pain, sensory disturbances, and mobility issues. This happens when they compress or irritate the surrounding nerves. Diagnosing and treating these spinal cysts requires a thorough understanding of their characteristics, causes, and effects on the body.
This guide explores the anatomy of Tarlov cysts, their causes and risk factors, common symptoms, diagnostic methods, and available treatment options. We aim to support those living with sacral cysts. Our goal is to help them navigate their journey toward improved well-being.
What is a Tarlov Cyst?
A Tarlov cyst is a fluid-filled sac that forms on the nerve roots of the spinal cord. It usually appears in the sacral region, which is the lower back area near the tailbone. These cysts are found near the dorsal root ganglion, where sensory nerve fibers enter the spinal cord.
The main features of Tarlov cysts are:
- Filled with cerebrospinal fluid (CSF)
- Lined with nerve fibers and nerve sheath cells
- Can range in size from a few millimeters to several centimeters
- May occur in clusters or as a single cyst
Location and Prevalence
Tarlov cysts often appear in the sacral region, mainly at the S2 and S3 levels. This can cause nerve root compression and symptoms. While they can also appear in other spine areas, like the thoracic or cervical, these are less common.
Studies suggest Tarlov cysts affect 4.6% to 9% of people. Yet, many with these cysts don’t show symptoms. Women are more likely to be diagnosed with Tarlov cysts than men, with a 2:1 ratio.
| Location | Prevalence |
|---|---|
| Sacral region (S2-S3) | Most common |
| Thoracic region | Less common |
| Cervical region | Rare |
Anatomy of the Spine and Sacral Region
It’s key to know how the spine and sacral area work to understand Tarlov cysts. The spine has 33 vertebrae, split into five parts: cervical, thoracic, lumbar, sacral, and coccygeal. The sacral area, at the spine’s base, is made of five fused vertebrae (S1-S5). These form a triangular bone called the sacrum.
Inside the sacral area, there are important parts:
| Structure | Description |
|---|---|
| Sacral canal | A part of the spinal canal that holds the spinal cord and nerve roots |
| Sacral foramina | Openings in the sacrum for nerve roots to exit |
| Sacral nerve roots | Nerves from the spinal cord that serve the lower back, buttocks, and legs |
| Filum terminale | A fibrous cord linking the spinal cord to the coccyx |
Tarlov cysts usually appear in the sacral area, near the S2-S4 nerve roots. These cysts can press on nerves, causing pain, numbness, or weakness. Sometimes, they can also damage the spinal cord, leading to serious neurological problems.
Because Tarlov cysts are close to nerves and the spinal cord, it’s vital to diagnose and treat them right. Knowing the spine and sacral area’s anatomy helps doctors understand Tarlov cysts’ effects. They can then create treatment plans to help patients.
Causes and Risk Factors of Tarlov Cysts
The exact causes of Tarlov cysts are not fully understood. But, several factors might play a role in their development. These include genetic predispositions, trauma to the spine, and congenital abnormalities.
Genetic Predisposition
Some people might be more likely to get Tarlov cysts due to their genes. Certain genetic changes could make nerve root sheaths more likely to form cysts. But, more research is needed to understand this link fully.
Trauma and Injury
Spinal trauma, like accidents or falls, can lead to Tarlov cysts. Damage to the sacral region can harm nerve root sheaths. This damage can help cysts form. Here’s a table showing how different traumas might affect Tarlov cysts:
| Type of Trauma | Potential Impact on Tarlov Cyst Formation |
|---|---|
| Whiplash injury | Stretching and tearing of nerve root sheaths |
| Compression fractures | Pressure on nerve roots, leading to cyst development |
| Spinal surgery complications | Inadvertent damage to nerve root sheaths during procedures |
Congenital Abnormalities
In some cases, Tarlov cysts are present at birth. This is due to spinal structure abnormalities. These can affect nerve root sheaths, making cysts more likely. Spina bifida occulta and tethered cord syndrome are examples of such abnormalities.
Knowing the causes and risk factors of Tarlov cysts is key. If you think you might be at risk, see a doctor. They can help with early detection and treatment.
Symptoms and Effects of Tarlov Cysts
Tarlov cysts, also known as sacral cysts or meningeal cysts, can cause a range of symptoms. These symptoms can greatly affect a person’s quality of life. The cysts develop along the nerve roots in the sacral region. They often lead to pain, discomfort, and various neurological symptoms.
Pain and Discomfort
Pain in the lower back, buttocks, and legs is a common symptom of Tarlov cysts. The pain can feel like a dull ache, sharp stabbing, or burning. Sitting or standing for a long time can make the pain worse. But lying down might offer some relief.
Neurological Symptoms
Tarlov cysts can compress nearby nerve roots. This can cause a range of neurological symptoms. These may include:
| Symptom | Description |
|---|---|
| Numbness or tingling | Sensation loss or pins and needles in the legs, feet, or buttocks |
| Weakness | Reduced strength in the lower extremities |
| Bladder or bowel dysfunction | Difficulty controlling urination or bowel movements |
| Sexual dysfunction | Pain or reduced sensation during intercourse |
Impact on Quality of Life
The pain and neurological symptoms from Tarlov cysts can greatly affect a person’s life. Many find it hard to do daily activities like walking or sitting. The pain and discomfort can also cause emotional distress, anxiety, and depression.
Getting a prompt diagnosis and proper treatment is key. It helps manage symptoms and improve overall well-being.
Diagnosis of Tarlov Cysts
Diagnosing Tarlov cysts involves imaging and physical exams. These methods help doctors find perineurial cysts in the lumbosacral area. They also check how these cysts affect nerves and tissues nearby.
Imaging Techniques (MRI, CT Scan)
Magnetic Resonance Imaging (MRI) is best for spotting Tarlov cysts. MRI scans show the spine in detail. This lets doctors see the cysts, their size, and how they relate to sacral nerve roots.
Computed Tomography (CT) scans are also used. They help see if the cysts have caused bone changes. CT scans show how the cysts affect the bone around them.
Physical Examination
A detailed physical exam is also key in diagnosing Tarlov cysts. People with these cysts might have lower back pain or nerve problems in the lumbosacral area.
Doctors check the patient’s nerve function, reflexes, and how they walk. They might also do tests to see if they can make the patient’s symptoms worse. Touching the lower back might show tenderness or a mass, which could be a Tarlov cyst.
By looking at imaging results and physical exam findings, doctors can accurately diagnose Tarlov cysts. They then decide the best treatment for each patient.
Treatment Options for Tarlov Cysts
Tarlov cysts, also known as spinal cysts or spinal cord lesions, have both surgical and non-surgical treatments. The right choice depends on the cyst’s size, location, symptoms, and the patient’s health.
Non-surgical treatments for Tarlov cysts include:
| Treatment | Description |
|---|---|
| Pain management | Medications, injections, or other techniques to control pain and discomfort |
| Physical therapy | Exercises and stretches to improve strength, flexibility, and function |
| Lifestyle modifications | Changes in posture, activity level, or ergonomics to reduce pressure on the affected area |
Surgery might be needed for Tarlov cysts in some cases. Surgery aims to relieve pressure on the spinal cord or nerve roots. This helps prevent further damage. Surgical options include:
- Cyst drainage and fenestration
- Cyst removal (cystectomy)
- Shunting procedures to divert fluid away from the cyst
Deciding on surgery for a Tarlov cyst should involve a neurosurgeon or orthopedic spine surgeon. Patients should weigh the risks and benefits of each option carefully before choosing.
Surgical Interventions for Tarlov Cysts
Tarlov cysts, also known as perineural cysts, sacral cysts, or meningeal cysts, can cause severe symptoms. If these symptoms greatly affect a patient’s quality of life, surgery might be needed. Surgery is usually considered when other treatments don’t work well or if the cyst worsens neurological problems.
