Is there a relationship between lumbosacral epidural spinal injections and lumbosacral epidural lipomatosis? A retrospective study.

Background: We aim to investigate the potential association between the administration of Lumbosacral epidural steroid injections (LESIs) and the subsequent onset or progression of Lumbosacral epidural lipomatosis (LEL) in patients devoid of established risk factors for LEL.

Methods: We carried out a single-center retrospective study on patients who underwent LESI. We collected demographics including age and gender as well as clinical and radiological characteristics including the type of corticosteroids utilized, the number of LESIs administered, the use of epidural guidance during LESI procedures, and LEL grading.
