原发性甲旁亢出现的多系统症状如纤维囊性骨炎、肾结石等都是由钙磷代谢紊乱造成的。因此,测定血钙和甲状旁腺素升高可以用来诊断本病。但是Boonstra报告在5万病人中有50例甲旁亢病人血钙高,却未发现甲旁亢的症状。Melvin报告在一些MEN2a型病例中,血钙水平和甲状旁腺素测定均正常,手术中却发现甲状旁腺增生。本文作者报告一例血钙正常的无症状的甲状旁腺腺瘤。患者女性,45岁,因发现甲状腺肿物进行性增大5年并有压迫症状而入院。患者否认有任何与甲旁亢
Multiple systemic symptoms of primary hyperparathyroidism, such as fibrocystic osteitis and kidney stones, are caused by calcium and phosphorus metabolism disorders. Therefore, determination of serum calcium and parathyroid hormone can be used to diagnose the disease. However, Boonstra reported that 50 of the 50,000 patients had hypercalcemia with hyperparathyroidism but no symptoms of hyperparathyroidism were found. Melvin reported that in some MEN2a cases, serum calcium levels and parathyroid hormone measurements were normal, but parathyroid hyperplasia was found during surgery. The authors report a case of asymptomatic parathyroid adenoma with normal serum calcium. The patient, 45 years old, admitted to hospital because she was found to have progressively increased thyroid mass for 5 years and had oppressive symptoms. The patient denied any side effects
