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

BACKGROUND

Hyperparathyroidism is a frequent affection. Therapeutic management is based on surgical removal of pathological glands. Therapeutic results are ameliorated thanks to preoperative imaging approach.

AIM: To evaluate performances of different imaging investigations and scintigraphy for preoperative parathyroid localization.

METHODS

Retrospective study about 26 patients with confirmed hyperparathyroidism.

RESULTS

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.

CONCLUSION

Our results compared to the literature showed that scintigraphy is the most satisfying for preoperative localization of abnormal parathyroid glands in hyperparathyroïdism.
