[Performances of imaging investigations and scintigraphy for pre operative hyperparathyroidism]

ABSTRACT

Hyperparathyroidism is a frequent affection. Therapeutic management is based on surgical removal of pathological glands. Therapeutic results are ameliorated thanks to preoperative imaging approach. To evaluate performances of different imaging investigations and scintigraphy for preoperative parathyroid localization. Retrospective study about 26 patients with confirmed hyperparathyroidism. After radio-surgical and histological correlation, scintigraphy showed the best rate of sensitivity [92.3%], compared to other morphologic imaging [ultrasonography 66.6%, CT-scan 33.3% and MRI 66.6%]. The specificity was the same [100%]. No difference was obseved for both scintigraphic modalities. Our results compared to the literature showed that scintigraphy is the most satisfying for preoperative localization of abnormal parathyroid glands in hyperparathyroidism
