Epidural lipomatosis complicating lumbar steroid injections

Corticosteroid injections into the spinal epidural space are frequently used to effect a relief of back pain and associated radicular extremity symptoms. Spinal epidural lipomatosis has been documented after the use of systemic corticosteroid therapy. This case report documents the development of epidural lipomatosis after the administration of multiple epidural steroid injections. The development and subsequent resolution after discontinuation of the steroid injections are demonstrated with serial magnetic resonance imaging.
