characteristic radiographic features of osteitis fibrosa attributable to secondary hyperparathyroidism
- Early: subperiosteal resorption in the hands, wrists, feet, and medial tibia, particularly on the radial side of the middle phalanx of the index and middle fingers osteoporosis.
- Intermediate: subchondral resorption of sternoclavicular, acromioclavicular, discovertebral, and sacroiliac joints and symphysis pubis; loss of the lamina dura around teeth; acroosteolysis of the phalangeal tufts; chondrocalcinosis of knees, wrists, and symphysis pubis periarticular and soft tissue calcification; osteosclerosis.
- Late: bone cysts
- Brown tumor: osteoclastomas with dried blood (brown); typically occur at the medial end of clavicles or skull, long bones, sternum, and spine.
- Subligamentous bone resorption: of trochanters, ischial tuberosities, humeral tuberosities, and calcanei.
