Synovial cysts constitute an uncommon degenerative lesion of the spine. They are usually asymptomatic but they may also cause symptoms of variable severity. The authors present three cases of such cysts, two in the lumbar region of a 55-year-old female and a 66 year old female and one in the cervical region of a 56-year-old male patient. All patients presented with radiculopathy. Magnetic Resonance Images revealed a cystic lesion at the L4/5 level in the first case, at L5/S1 level in the second case and at the C7/T1 junction level in the third case. Treatment has been microsurgical resection of all cysts with no post-operative complications and an excellent outcome. A discussion of current management options for this unusual disease is presented and a decision making flow chart is proposed.
