Spinal cysts are fluid-filled tumors on or near the spine. They are most common in the sacral (tailbone) area. Spinal cysts are also called perineural cysts, sacral nerve root cysts or Tarlov cysts.
Many spinal cysts don't cause any symptoms. However, a spinal cyst may cause symptoms if it's large or located where it presses on nearby nerves. This can cause:
- Leg weakness
- Loss of bladder or bowel control
Spinal cysts tend to get larger over time. If a cyst causes symptoms, your doctor might recommend surgery to remove it. The OHSU Spine Center doctors are experts at treating spinal cysts.
