Steroid-induced spinal epidural lipomatosis: CT survey.

A new case of spinal cord compression secondary to steroid-induced epidural lipomatosis is reported in a patient treated for dermatomyositis. Computed tomography was performed before the institution of steroid therapy, during spinal cord compression, and after effective surgical treatment. The development of epidural lipomatosis does not require a preexisting lipoma and may occur in a previously normal spine.
