Acute Pancreatitis Revealing Primary Hyperparathyroidism Due to Unilateral Parathyroid Hyperplasia Associated with Parathyroid Adenoma

Primary hyperparathyroidism is a common endocrine pathology characterized by elevated levels of parathyroid hormone, the most common clinical manifestations being renal or skeletal damage accompanied by moderate or severe hypercalcemia. Around 80-85% of primary hyperparathyroidism cases are caused by a single parathyroid adenoma, 4-5% by multiple adenomas, 10-15% by parathyroid hyperplasia and less than 1% by parathyroid carcinoma. We report the case of a patient with primary hyperparathyroidism presenting with acute pancreatitis. After cooling of the pancreatitis, the patient underwent surgery. Post-operative follow-up showed definitive hypocalcemia, and pathological examination revealed the association of parathyroid hyperplasia and a unilateral parathyroid adenoma.
