Abstract
The new term of ‘Chronic Kidney Disease- Mineral and Bone Disorders’ has been introduced to encompass a wide-ranging syndrome, capturing various abnormalities in bone and mineral metabolism seen in patients with chronic kidney disease. Multifactorial disorders affecting mineral metabolism and bone structure emerge early in the progression of Chronic Kidney Disease. Brown tumors, an uncommon type of bone lesion are distinctive manifestations of high-turnover bone disease. In this case, a patient with chronic kidney disease (dialysis dependent) with IgA nephropathy that presented with multiple osseous lesions of bilateral ribs, sternum, scapula, clavicle, mandible and vertebral bodies. The case highlights the significance of considering brown tumors in the differential diagnosis and management of patients with both an osseous mass and chronic kidney disease. Failing to establish an accurate diagnosis may result in unnecessary additional diagnostic procedures and extensive surgery, ultimately increasing patient morbidity. Through this case report, the importance of preventing, early diagnosing, and treating secondary hyperparathyroidism to reduce the prevalence of high-turnover bone disease and associated complications such as brown tumors is emphasized.
