Low back pain in a diabetic on chronic haemodialysis: pyogenic spondylodiscitis.

Spondylodiscitis of the lumbar spine is described in a 67-year-old-man receiving chronic haemodialysis via a central venous catheter for diabetic nephropathy. He also had a forearm arteriovenous fistula created 1 month earlier. Clinical, MRI and surgical findings are described. The patient died despite spinal surgery and 1 month of antibiotic therapy from suspected pulmonary embolism. Early recognition by MRI or other imaging technique, prompt antibiotic therapy and often surgery are necessary for a successful outcome in this increasingly recognised complication in patients on chronic haemodialysis. Diabetes mellitus may be an added risk factor.
