title: Midline lumbar ganglion/synovial cyst mimicking an epidural tumor: case report and review of pathogenesis.
abstract: A case of a midline lumbar extradural ganglion/synovial cyst causing lumbar canal stenosis and mimicking an epidural tumor is presented. The lesion was demonstrated by a magnetic resonance imaging study, and relief of symptoms was achieved with decompressive laminectomy and total removal of the mass. The pathogenesis of lumbar ganglion/synovial cyst is reviewed.
