Synovial cysts are benign, fluid-filled sacs that develop in the facet joints of the lumbar spine as a result of degeneration. If large enough, these sacs can cause spinal stenosis.
In some patients, small amounts of the fluid escape from the joint capsule but remain within the synovium, creating a sac-like protrusion. Many older patients have synovial cysts in their lumbar spines but have no symptoms. Occasionally, however, these cysts can cause pain in the lower back that travels down the legs. The pain is relieved when sitting as this position widens the spinal canal and relieves pressure on the nerves. A synovial cyst can be seen on a. MRI.
