Unusual case of lumbar synovial cyst

Synovial cysts are extradural degenerative lesions associated with symptoms of lower back pain and radiculopathy. To our knowledge, all the reported c ases of synovial cysts in literature were posterolateral in location (1-4). This case report describes the previously unreported midline location of t he synovial cyst in the spinal canal and to increase the level of awareness of diagnosing these lesions in a central location, especially in light of the evaluation of lumbar radiculopathy.
