Сложности диагностики первичного гиперпаратиреоза у пациента с эктопированной в средостение аденомой околощитовидной железы и полиоссальной фиброзно-кистозной остеодистрофией

Abstract

Objective of the Paper: To demonstrate a rare variant of primary hyperparathyroidism in a patient with mediastinal ectopic parathyroid adenoma and polyossal fibrocystic osteodystrophy using a clinical example. Key points. Fibrocystic osteodystrophy is a specific manifestation of primary hyperparathyroidism, which in modern conditions belongs to the casuistically rare. Ectopia of the parathyroid gland into the mediastinum also refers to rare variants of the location of this organ. Our patient's attention is drawn to the poor clinical picture with the rapid development of bone changes. Conclusion. The variety of clinical manifestations of primary hyperparathyroidism, low awareness and alertness of doctors of related specialties in relation to this disease leads to an increase in the time of diagnostic search, the formation of incorrect diagnostic and therapeutic concepts. Determination of plasma calcium level is sufficient, in most cases, to exclude or confirm the diagnosis of primary hyperparathyroidism. Keywords: primary hyperparathyroidism, parathyroid adenoma, ectopic parathyroid adenoma, osteitis fibrosa cystica, brown tumor.
