Tarlov cysts are abnormal sacs of spinal fluid that usually form at the lower end of the spine, which is called the sacrum. Tarlov cysts contain spinal nerve fibers within the cyst wall.

The cause of a Tarlov cyst is unknown but may be related to: Trauma
to the spine
Increase in cerebrospinal fluid pressureBlockage of cerebrospinal fluid
Although gender may not be a risk factor, Tarlov cysts have more often been found in women than men.
Tarlov cysts may be linked to connective tissue disorders such as
systemic lupus erythematosus
Most of the time, Tarlov cysts do not cause symptoms. When symptoms do occur, they may include: Bladder or bowel dysfunctionSexual dysfunctionNerve painPain in the lower back, buttocks, legs and feet, vagina, rectum, or abdomenPain when coughing or sneezingWeakness, cramping, or numbness in the buttocks, legs, and feetSwelling, soreness, or tenderness around the lower end of the spineAbnormal sensations in the legs and feet, or less commonly in the arms and handsPain when sitting or standingHeadachesPulling and burning feeling in the tailboneLoss of sensation on the skinLoss of reflexes
If you have a Tarlov cyst, the following may cause it to become painful or cause other symptoms: Traumatic injury
such as a fall, automobile accident
Heavy liftingChildbirthEpidural anesthesiaGrowth of the cyst
You will be asked about your symptoms and medical history. A physical exam will be done. Depending on your symptoms, you may need to see a specialist, such as a neurosurgeon.
Images may be taken of your bodily structures. This can be done with: MRI scanCT scanMyelogram
If you are experiencing symptoms, talk with your doctor about the best treatment plan for you. Options may include:
To relieve inflammation and/or pain: Over-the-counter or prescription pain relievers, such as nonsteroidal anti-inflammatory drugs (NSAIDs)Topical pain relievers that are applied to the skinCorticosteroid or other medicated injections
Other treatments may include: Aspiration of the cyst plus fibrin glue injection—a needle is used to drain the cyst and then a special glue is injected into the cyst to try to prevent it from filling againTranscutaneous electrical nerve stimulation (TENS)—electrical impulses delivered through the skinSurgery may be done for severe or worsening symptoms, bowel or bladder dysfunction, or if there is damage to the affected area
There are no current guidelines to prevent a Tarlov cyst.
