I am a 70 year old woman who had a synovial cyst of the spine about 5 years ago. The only symptom I had was leg pain. The cyst was diagnosed after doing physical therapy and when that was unsuccessful having a MRI. Recently, a similar pain has begun in the same area as when I experienced the synovial cyst. Is it possible that a cyst could reoccur in the same location?
Hi there. Thanks for your question at Chat Doctor.  Synovial is the normal covering of joints which help in production of joint build and smooth functioning of joints. Synovial cysts are fluid filled lesions, arising from stadium of joints which have worn out. Age related arthritis in joints of at the back of your spine (facet joints) can lead to synovial cysts which can manifest with pain in the lower limbs(since these joints are pretty close to your nerves in the spine. As long as the joints are still present (that is no fusion or fixation surgery done for these joints) these cysts can persist and can recur. So the answer for your question is, yes it is possible for it to recur in same location, if that particular joint was not fused last time around. If the pain is bothering you, the best way to confirm this would be a repeat MRI of your spine. Its OS best that you see your doctor and confirm that your current symptoms are matching the findings of spinal involvement and get further evaluated.  Hope this helps.  All the best.  Regards.  Chat Doctor.
