Although gender may not be a risk factor, Tarlov cysts have more often been found in women than men.
Most of the time Tarlov cysts do not cause symptoms. Cysts may cause pain and other signs of nerve irritation, such as weakness or numbness. In some cases, it can cause problems with bladder and bowel function.
An increase in pressure in or on the cyst may increase symptoms and cause nerve damage. Symptoms can vary from person to person.
