Tarlov Cysts: Symptoms, Risks, and Treatment Options - Orthopedics

More Info

---

Tarlov cysts, also known as perineural cysts, are fluid-filled sacs that typically develop in the sacral region of the spine. They are often discovered incidentally during imaging studies, such as MRI, and can vary in size. While many individuals with Tarlov cysts remain asymptomatic, some may experience symptoms due to nerve compression or irritation, particularly if the cysts are large or located in a sensitive area.


Symptoms
The symptoms associated with Tarlov cysts can include:
- Pain: This may manifest as lower back pain, sciatica, or pain radiating down the legs, particularly in the calves and feet.

- Numbness and Tingling: Patients may experience numbness, tingling, or a "pins and needles" sensation in the legs or feet.

- Weakness: Muscle weakness in the legs, especially in the calves, may occur.

- Bowel and Bladder Dysfunction: In some cases, Tarlov cysts can affect bowel and bladder control, leading to incontinence or retention issues.


Risks
While Tarlov cysts are generally benign, there are risks associated with their presence:
- Compression of Nerves: If the cysts grow large enough, they can compress nearby nerves, leading to significant pain and neurological symptoms.

- Potential for Growth: Although not all Tarlov cysts grow, some may increase in size over time, potentially exacerbating symptoms.

- Surgical Risks: If surgery is deemed necessary, there are inherent risks, including infection, bleeding, and the possibility of not achieving symptom relief.


Treatment Options
1. Conservative Management: Many patients with Tarlov cysts do not require surgery. Conservative treatments may include:
- Physical Therapy: As you mentioned, physical therapy can help strengthen the muscles around the spine and improve flexibility, potentially alleviating some symptoms.

- Pain Management: Over-the-counter pain relievers, such as NSAIDs (e.g., ibuprofen), may help manage pain. In some cases, prescription medications may be necessary.

- Epidural Steroid Injections: These can provide temporary relief by reducing inflammation around the affected nerves.

2. Surgical Intervention: Surgery is typically considered when conservative measures fail, and the cysts are causing significant symptoms. Surgical options may include:
- Cyst Excision: This involves removing the cyst, which may relieve pressure on the nerves.

- Laminectomy: In some cases, a laminectomy may be performed to relieve pressure on the spinal cord or nerves.


When to Consider Surgery
Surgery may be indicated if:
- Symptoms significantly impair daily activities or quality of life.

- There is progressive neurological deficit or worsening symptoms.

- Conservative treatments have been exhausted without relief.


Prognosis
The prognosis for individuals with Tarlov cysts varies. Many patients find relief with conservative management, while others may require surgical intervention. It is essential to have ongoing discussions with your healthcare provider to monitor the cyst's size and your symptoms. Regular follow-ups and imaging may be necessary to assess any changes.


Conclusion
In summary, Tarlov cysts can cause a range of symptoms, particularly if they compress nearby nerves. While many individuals remain asymptomatic, those experiencing significant discomfort should work closely with their healthcare team to explore treatment options. Physical therapy and pain management are often effective first steps, while surgery may be necessary for more severe cases. Always consult with a healthcare professional for personalized advice and treatment plans tailored to your specific condition.
