Osteitis fibrosa cystica is also known as which of the following conditions?

Osteitis fibrosa cystica is primarily associated with primary hyperparathyroidism, a condition characterized by excessive secretion of parathyroid hormone (PTH) from the parathyroid glands. This increase in PTH leads to elevated calcium levels in the blood and results in a distinctive skeletal manifestation due to increased osteoclastic activity.

In osteitis fibrosa cystica, there is a resorption of bone leading to the formation of cyst-like spaces, often described as "brown tumors" of the bone due to the accumulation of fibrous tissue, hemorrhage, and osteoclast activity. The clinical significance of primary hyperparathyroidism is crucial here since it directly causes osteitis fibrosa cystica, marking it as an important condition in the differential diagnosis of bone disorders related to parathyroid hormone secretion.

Other options reflect different metabolic conditions but do not specifically relate to the etiology or manifestations associated with osteitis fibrosa cystica. For example, secondary hyperparathyroidism arises due to chronic kidney disease but does not typically result in the same bone changes as primary hyperparathyroidism. Osteoporosis is characterized by reduction in bone density and structural deterioration but is distinctly different in pathophysiology. Hypoparathyroidism may lead
