A NUMBER of bone diseases may affect the orbital bones decreasing the orbital volume and narrowing the optic canal, giving rise to unilateral exophthalmos and usually optic atrophy, simulating clinically an orbital tumour. Among such diseases are osteitis deformans (Paget, 1876); leontiasis ossea (Virchow, 1896); osteopetrosis (Albers-Schonberg, 1904), and the generalized and localized osteitis...

BMJ Case Reports Published online: [please include Day Month Year] doi:10.1136/ bcr-2012-008086 DESCRIPTION The case of a patient with primary hyperparathyroidism with classic and severe skeletal involvement has been previously reported. Briefly, it was the case of a 63-year-old woman who presented with multiple repeated fractures, the latest of which were of both femoral...

number, and an increase in the number of osteoclastic Introduction resorption bays demonstrating the increased rates of bone resorption in osteitis fibrosa. Renal osteodystrophy is the term used to describe the In addition, osteitis fibrosa is characterized by a skeletal complications of end-stage renal disease. It is prominent accumulation of fibroblastic cells around a multifactorial disorder...

The case is described of a woman who died with a functioning parathyroid carcinoma 19 years after removal of two parathyroid tumours, considered at the time to be benign. Following operation hyperparathyroidism subsided, with a short period of hypocalcaemia, and severe osteitis fibrosa cystica healed. Five years before death progressive renal failure developed with normal and later raised serum...

THE diagnosis of primary hyperparathyroidism has been classically based upon the demonstration of high plasma calcium and low plasma phosphorus concentrations and an excessive urinary excretion of calcium. In recent years, however, it has become recognized that patients with primary hyperparathyroidism may present with plasma calcium concentrations that are within the normal range (George et al...

Changes in mineral and bone metabolism are prevalent in chronic kidney disease. There are several types of renal bone disease, called 'renal osteodystrophy (ROD)'. ROD includes osteitis fibrosa, osteomalacia, adynamic bone disorder, and mixed osteodystrophy. Osteitis fibrosa is high turnover bone due to secondary hyperparathyroidism. Osteomalacia is low turnover bone concomitant of increased os...

With advances in the treatment of patients with chronic renal failure, their life expectancy has increased. In turn, the prevalence of osteitis fibrosa cystica, a manifestation of secondary hyperparathyroidism, and beta2 microglobulin amyloidosis, a result of long-term haemodialysis, has risen. While both conditions share similar radiological features, their management is very different. We pre...
