The authors present the results of clinicoroentgenological and biochemical investigations in 102 patients with chronic renal insufficiency after hemodialysis and in 76 patients after kidney transplantation. The nature of secondary hyperparathyroid fibrous osteodystrophy and osteomalacia as main symptoms of nephrogenic osteodystrophy (NO), their interrelation and correlation are analysed. Of 178 patients pathological changes of the bone system were revealed in 94 (52.9%). The combination of fibrous osteodystrophy and osteomalacia (22%) is regarded as a contraindication for parathyroidectomy. Effective kidney transplantation does not prevent NO though its specificity changes: osteomalacia is more marked, osteonecrosis and soft tissue calcification are more common. The chief method of radiodiagnosis of NO is routine radiography of the skeleton supplemented by small feature contact radiography and x-ray image color analysis on the UAR and TELEVAN TV units. Comparative roentgenodensitometry of the bones and CT of the parathyroid glands contributed to obtaining objective information but was of applied value.

Article Synopsis
- Leontiasis ossea, or craniofacial fibrous dysplasia, is a rare condition that causes abnormal growth of facial bones, often linked to chronic kidney disease and high parathyroid hormone levels.
- A case of a 30-year-old male with severe facial swelling and bone changes highlights the rapid progression of symptoms after poor dialysis access and the persistence of hyperparathyroidism despite treatment efforts.
- The article also reviews the underlying causes, imaging techniques used for diagnosis, and management strategies for this complex disease.

Brown tumors or osteitis fibrosa cystica are a rare bone metabolism disorder that may mimic cancer metastasis. It represents a late manifestation of prolonged and mostly unrecognized hyperparathyroidism. In this case report we present a 44-year-old female patient with multiple lesions detected on bone scintigraphy and F- FDG-PET/CT, initially interpreted as a bone metastatic disease, rather than multiple gigantocellular bone tumors.

Typically, primary hyperparathyroidism (PHPT) develops as a result of multiglandular hyperplasia, parathyroid cancer, or parathyroid adenoma. Patients usually present with skeletal manifestations such as low-trauma fractures. Osteitis fibrosa cystica (OFC) is a classic yet rare skeletal manifestation of advanced PHPT currently reported in less than 2% of patients.

Background: Brown tumors are rare bone manifestations of primary hyperparathyroidism (PHPT) that may occur at different sites either as single or multiple lesions and they can easily be mistaken for malignant lesions. Neither bone site nor morphological or functional imaging are useful to drive the differential diagnosis and biopsy is often the only conclusive procedure.
Case Description: We report the case of a 53 years-old man referred to our outpatient clinic for severe symptomatic PHPT complicated by nephrolithiasis and osteoporosis.
