The presence of the synovial cyst makes me think there might be an associated degenerative spondylolisthesis (see website) associated with this problem. Synovial cysts develop in degenerating facet joints and these joints can break down leading to the slip of one vertebra on the other.

In addition, recurrence of these cysts can occur in about 10% of operated patients. Recurrent disc herniations also have about a 10% recurrence rate.

A new MRI is warranted along with standing X-rays including flexion/extension views. This will determine what new or recurrent pathology has occurred.
