Comparison of roentgenological and histological features of bone changes in primary hyperparathyroidism.

Fifteen cases of bone disease in primary hyperparathyroidism were investigated by comparing X-ray findings with metabolic data and histological features. Besides the usual features of subperiosteal resorption, diffuse demineralization and localized destruction, the less common features of osteosclerosis, and the infrequently described response of the growth plate were also demonstrated. The bone changes in roentgenographs were graded on a five point scale, 0-IV. All cases in Grade IV had parathyroid cancers and extremely high serum and urinary calcium values.
