Osteitis fibrosa

Osteitis fibrosa cystica; Hyperparathyroidism - osteitis fibrosa; Brown tumor of bone

Osteitis fibrosa is a complication of hyperparathyroidism, a condition in which overactive parathyroid glands cause certain bones to become abnormally weak and deformed.

Parathyroid glands

The 4 parathyroid glands are located near or attached to the back side of the thyroid gland and produce parathyroid hormone. Parathyroid hormone regulates calcium, phosphorus, and magnesium balance within the blood and bone by maintaining a balance between the mineral levels in the blood and the bone.
