OBJECTIVE: This article presents a case in which synovial cysts appeared to cause compromise of the neural foramina and thecal sac with presenting neurological signs. CLINICAL FEATURES: A 67-year-old female patient with a history of lumbar synovial cysts and synovectomy presented with recurrence of bilateral low back, leg pain, and apparent neurological compromise along with a recurrence of lumbar synovial cyst as evidenced on magnetic resonance images. INTERVENTIONS AND OUTCOME: Flexion distraction therapy, performance of Williams low back exercises and interferential therapy resulted in 50% relief. Frequency of care was progressively diminished as she improved. The patient experienced recurrence of severe episodes; multifidi strengthening exercises were provided to address a concomitant spondylolisthesis and instability, resulting in a cessation of these episodes and improvement in functional activities. CONCLUSION: Distraction therapy seemed to alleviate the constant pain without surgical intervention. In this case, the synovial cyst may have been an incidental finding versus a primary cause of the low back and leg pain. For similar patients, in the absence of correlative progressive neurological signs, surgical intervention may not be necessary.
