Objective And ImportanceSpinal epidural lipomatosis, which causes symptomatic compression of neural elements, is a well known but uncommon complication of Cushing's syndrome. Spinal epidural lipomatosis has been reported frequently in association with chronic systemic corticosteroid therapy, but thus far only one case has been attributed to local epidural corticosteroid injections.Clinical PresentationWe report another case of symptomatic spinal epidural lipomatosis after epidural corticosteroid injections. This is the first such case documented by magnetic resonance imaging and confirmed with surgical exploration.InterventionThe patient's symptoms of neurogenic claudication resolved after lumbar laminectomy in the region of previous corticosteroid injections and the removal of epidural fat, which was compressing the thecal sac.ConclusionThis case should alert clinicians that epidural lipomatosis, which causes symptomatic thecal sac compression, is a possible complication, not only of systemic glucocorticoid therapy, but also of local epidural corticosteroid injections.
