Parathyroid apoplexy, the explanation of spontaneous remission of primary hyperparathyroidism: a case report

Primary hyperparathyroidism due to parathyroid adenoma represents an endocrine disease that is usually treated by surgical intervention (parathyroidectomy). In a very few patients, primary hyperparathyroidism can be spontaneously remit either by infraction or hemorrhage of the adenoma,a fact that is almost certain that will not lead to complete and definite cure. We describe a similar case of a 59-year-old male patient who underwent surgery for a cystic degeneration of a parathyroid adenoma, with substantial preoperative reduction of parathyroid hormone and calcium serum levels,and the diagnostic and treatment modalities are discussed, with a brief review of the current literature.
