[Reoperation because of ectopic parathyroid adenoma with previous removal of lipothymoma. Importance of intraoperative PTH].

Sometimes the surgery of hyperparathyroidism is not easy and the surgical team find difficulties to locate the pathological gland or glands. We report a case of primary hyperparathyroidism due to an ectopic parathyroid adenoma which required two interventions. First we removed what it seems an adenoma but resulted to be a lipotimoma. In the reintervention practiced one week later, having then the rapid or turbo intraoperative PTH and previous digital scintigraphy, it was possible to remove an adenoma histologically confirmed, with 3,5 cm diameter located in depth to right thyroid lobe towards the superior mediastinal straits. The postoperative evolution of the patient was satisfactory and no complications were registered.
