Summary We report a rare case of an immunoglobulin D (IgD) myeloma mass that occupied the lumbar epidural space. The patient presented with paraparesis combined with an extremely high concentration of serum IgD, and azotemia. A complete remission was obtained after combination chemotherapy, but the patient died from an epidural tumor in the high thoracic region 19 months after the onset of symptoms.
