Osteosclerosis in primary hyperparathyroidism

Abstract

Osteosclerosis in adults with primary hyperparathyoidism is rare; the usual skeletal manifestation, when presented, is diffuse osteropenia. We describe a patient with generalized osteosclerosis in association with primary hyperparathyroidism. The findings are documented by conventional and fine-detail radiography, absorptiometric bone mineral analysis, quantitative microradiography and histologic examination of bone. The unique features are contrasted with the manifestations recorded in a recently studied group of 87 hyperparathyroid patients. The data presented here support a causal relationship in this patient between parathyroid hormone excess and the development of densely sclerotic bones.
