title: Primary hyperparathyroidism. Report of a clinical case without bone lesions.
abstract: A 26-year-old woman was admitted to the Institute of Endocrinology in Bucharest for evaluation of primary hyperparathyroidism (P-HPT). Anamnesis revealed a 10-year history of nephrolithiasis; peptic ulcer, chronic pancreatitis, cholelithiasis. Eight months previously, she had given birth to a child who had neonatal hypocalcaemic tetany. Investigations revealed the presence of moderate hypercalcaemia, hypercalciuria, hypo-phosphoremia; serum chloride level was above 100 mEq/1, and the chloride phosphate ratio was greater than 33. X-ray films of the abdomen revealed the presence of nephrolithiasis and right nephrocalcinosis. Selenium methyonine scanning, ultrasonography and computerized tomography were negative. On surgical exploration a 2-3 cm parathyroid adenoma was removed from between the trachea and the esophagus.
