JIMENEZ-HOYUELA, J. M. et al. Diagnostic and localization of the hyperparathyroidism by nuclear medicine procedures. An. Med. Interna (Madrid) [online]. 2003, vol.20, n.3, pp.35-38. ISSN 0212-7199.

Primary hyperparathryoidism is a PTH hypersecretion caused by the parathyroid glands. In most cases (85%), the origin is to be due to the existence of a parathyroid adenoma, despite the intrinsic difficulty in being localized under certain circumstances. From some time now, we can count with the invaluable help of a nuclear medicine technique, namely the parathyroid scintigraphy with Technetium 99m-sestamibi (Tc99m-MIBI), a technique wich is easy to perform, cheap and with excellent results, and wich additionally can provide us with the above mentioned necesary information regarding location. We present here the case of a patient suffering from primary hyperparatyiroidism, in whom both the disease and the precise location of the hyperfunctioning tissue were identified by means of the parathyroid scintigraphy. Another nuclear medicine procedure, the one known as bone scintigraphy, also contributed meaningfully to the correct diagnosis in the same patient.
