Abstract
We report four patients who had lumbago resistant to conventional treatment. The initial X-ray examinations and MIR findings suggested that the lumbago seemed to be caused by benign vertebral compression fracture; however, later bone marrow examination revealed that the lumbago was caused by multiple myeloma. Among the four patients, three were aged > 70 years older. Laboratory examinations revealed anemia, thrombocytopenia, and hyperproteinemia. Multiple myeloma should be borne in mind when conventional treatments do not relieve lumbago in older patients.
