Renale Osteodystrophie

Renal
osteodystrophy: A 57-year-old female with end-stage renal disease which results in prominent subchondral resorption resulting in widening of bilateral sacroiliac joints along the iliac surface on AP view of the pelvis (solid arrows). Soft tissue calcifications adjacent to right greater trochanter (dashed arrows), vascular calcification adjacent to the left femoral head (double dashed arrows), and a right femoral dialysis catheter.

Renal
osteodystrophy: Prominent trabecular pattern secondary to generalized trabecular resorption in a 32-year-old male with end-stage renal disease. Sclerotic bands adjacent to the vertebral endplates result in subtle “rugger jersey spine” secondary to the excess osteoid.

Renal
osteodystrophy: AP view of the pelvis (a) in a 26-year-old female with secondary hyperparathyroidism that results in multiple, circumscribed, and expanded lucent areas compatible with brown tumors. Associated fracture deformity of the right femoral head and generalized demineralization.

X-ray of
periosteal reaction in renal osteodystrophy. The subject is a 33-year-old male with end-stage renal disease and tertiary hyperparathyroidism. There is a thin periosteal reaction and cortical tunneling on the femur.

maketh the sign. Bone scintigram in a 25-year-old man with renal failure and arthralgia. A frontal planar image (a) and magnified view (b) demonstrates expansion of the manubrium and sternum without manubriosternal joint expansion resulting in a necktie appearance. In addition, a prominent calvarium and faint visualization of the kidneys are also supportive of a diagnosis of renal osteodystrophy

review of skull lesions. Renal osteodystrophy and osteopenia. Patient 1: Axial (a) and coronal (b) head CT images depict granular de-ossification with a “pepper pot” appearance (thick arrows) and loss of distinction of the inner and outer tables (dashed arrows) in this patient with renal osteodystrophy. Patient 2: Axial (c) and coronal (d) head CT images show demineralisation of the skull (arrowheads) in this patient with osteopenia. Note the relative preservation of the distinction of the inner and outer tables in osteopenia

Renal osteodystrophy (ROD), also known as uremic osteopathy, is a 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
  • aluminum intoxication, e.g. if the patient is on dialysis

Radiographic features

Imaging findings are many and varied:

Differential diagnosis

General imaging differential considerations include
