Unusual presentation in a case of primary hyperparathyroidism
نویسندگان
چکیده
This report describes a case of classic severe primary hyperparathyroidism (PH) with clinical presentation that is very infrequent nowadays, which was osteitis fibrosa cystica. As bone scintigraphy demonstrated multiple areas of increasing uptake associated with hypercalcemia, a thorough investigation was conducted to exclude the neoplasms which most frequently are responsible for bone secondarisms. A fludeoxyglucose (FDG) positron emission tomography/CT demonstrated diffuse and multiple foci of increased FDG uptake and a focal uptake at the left thyroid region. Parathyroid function was studied, revealing unexpectedly high parathyroid hormone (PTH) levels. Further tests confirmed the diagnosis of PH and localized a parathyroid adenoma in the lower left side.

BACKGROUND Primary hyperparathyroidism is an endocrinopathic condition characterized by hypersecretion of parathyroid hormone. Excess parathyroid hormone results in an altered state of osseous metabolism involving bone resorption and tissue change known as osteitis fibrosa cystica, which is the end stage of primary hyperparathyroidism. Osteitis fibrosa cystica is associated with the development...
