A: Magnified x-ray of index finger on fine-grain industrial film showing classicsubperiosteal resorption in a patient with severe primary hyperparathyroidism. Note theleft (radial) surface of the distal phalanx, where the cortex is almost completelyresorbed, leaving only fine wisps of cortical bone.
B: Skull x-ray from a patient with severe secondary hyperparathyroidism due to end-stagerenal disease. Extensive areas of demineralization alternate with areas of increasedbone density, resulting in the "salt and pepper" skull x-ray.
