A proposal of degenerative anterior epidural cysts of the lumbar spine
Anterior, benign epidural cysts are a rarely described cause of non discal lumbar radiculopathy. The differentiation between synovial, ganglion, fibrous annulus, posterior longitudinal ligament and disc cysts reflects the fragmentary nature of reports so far and it's probably misleading. A case of ventral L5-S1 synovial cyst is reported and the literature is reviewed. It is proposed that these lesions be all grouped together as anterior epidural degenerative cysts of the lumbar spine on the ground of shared clinical and MRI features and management options along with a common pathogenesis (response to degenerative spinal changes) and histological substrate.
