[Scintigraphic preoperative localization of abnormal parathyroid gland].

UNLABELLED: THE AIM of this study is to evaluate the accuracy of scintigraphic preoperative localization of abnormal parathyroid gland.

METHODS

25 patients with confirmed hyperparathyroidism undergone scintigraphic and ultrasound localization prior to surgery. Paratthyroid scintigraphy was done with thallium - techetium substraction and technetium-tetrofosmin dual phase techniques.

RESULTS

scintigraphic sensitivity and specificity was 83% and 100%. In primary hyperparathyroidism the sensitivity was 91% vs 75% in secondary one. Multinodular goiter affected sensitivity (72%). Ultrasound had an overall sensitivity of 66 % and a specificity of 100%.

CONCLUSION

parathyroid scintigraphy is non invasive, accurate and costeffective in localizing abnormal parathyroid gland especialy adenoma.
