Case Discussion
The patient had a history of renal failure and dialysis. Now she complained of right mandibular swelling.
Renal osteodystrophy (ROD), also known as uremic osteopathy, is the constellation of musculoskeletal abnormalities that occur in patients with chronic renal failure, due to concurrent and superimposed:
- osteomalacia (adults) / rickets (children)
- secondary hyperparathyroidism: abnormal calcium and phosphate metabolism
- bone resorption
- osteosclerosis
- soft tissue and vascular calcifications
- brown tumors
