[Skeletal manifestations of primary and secondary hyperparathyroiditis. Differential radiological diagnostic problems].
Primary and secondary hyperparathyroidism are both marked by widespread skeletal demineralisation, subperiosteal erosion of the cortex, brown tumours, osteosclerosis, and extraosseous calcification. Differential diagnosis is guided by the different association of these findings. Brown tumours and more extensive erosion are marks of the primary form, whereas osteosclerosis and extra-osseous calcification are a prominent feature of secondary hyperparathyroidism. Radiologists, therefore, should direct their attention to features suggesting the presence of secondary forms in addition to looking for bone alterations associated with hyperparathyroidism.
