ABSTRACT
RESUMEN La paratiromatosis se describe como una dolencia en la que existen múltiples nódulos de tejido paratiroideo hiperfuncionante diseminados por cuello y el mediastino, en la cual las pruebas de imagen no son efectivas para localizar las glándulas paratiroides y requiere de la combinación de un tratamiento médico y quirúrgico que en ocasiones se presenta como un desafío. Describimos el caso de una mujer de 61 años con hiperparatiroidismo primario recurrente a la que se le extirpan un total de 9 glándulas paratiroideas en 3 cirugías diferentes, y realizamos revisión de la literatura.
ABSTRACT Parathyromatosis is described as a condition in which there are multiple nodules of hyperfunctioning parathyroid tissue disseminated by the neck and mediastinum. Imaging tests are not effective in locating the parathyroid glands and requires the combination of medical and surgical treatment that sometimes is challenging. We describe the case of a 61-year-old woman with recurrent primary hyperparathyroidism. A total of 9 parathyroid glands where removed in 3 different surgeries. We also reviewed the literature.

Objective To evaluate 99Tcm-MIBI imaging in patients with hyperparathyroidism and its correlation with serum intact PTH level. Methods Seventy patients with suspicious hyperparathyroidism underwent 99Tcm-MIBI imaging and serum intact PTH measurement. Abnormal increased uptake lesion appeared at early phase and even more clearly at delayed phase was considered as the positive by 99Tcm-MIBI imaging. A cut-off value of PTH ＞ 88 ng/L was taken as the criteria for hyperparathyroidism diagnosis. The diagnostic efficacy of 99Tcm-MIBI imaging combined with serum PTH measurement was assessed according to post-surgical histopathology or clinical follow-up. For those operated patients, Pearson correlation coefficient between serum PTH and the gland volume was calculated. Results Hyperparathyroidism was confirmed in 38 patients by histopathology (n = 36) or follow-up (n = 2). The overall diagnostic accuracy of 99Tcm-MIBI imaging was 90.0% (63/70), in which the accuracy was 80.0% (12/15) for patients with normal serum PTH and 92.7% (51/55) for those with elevated serum PTH. False positive 99Tcm-MIBI imaging were found in 3 patients with normal serum PTH. The diagnostic accuracy of abnormally high serum PTH combined with 99Tcm-MIBI imaging was 94.3% (66/70). There was a positive correlation between serum PTH level and the volume of pathologic parathyroid glands (r = 0.782, P ＜ 0.001 ). Conclusions Serum PTH measurement may help to improve the diagnostic accuracy of 99Tcm-MIBI imaging in patients with hyperparathyroidism.
ABSTRACT
Objective To explore the diagnosis and treatment of primary hyperparathyroidism (PHPT). Methods Clinical data of 35 cases of PHPT were retrospectively analyzed. Results 23 out of 26 cases (88.5%) undergoing preoperative ultrasonography with a positive result were verified by intraoperative (findings). For ECT, the positive rate was 21 out of 23 cases (95.5%). Unilateral neck explorations (UNE) was performed in 27 cases of parathyroidoma. Two cases of parathyroid hyperplasia were treated by UNE and the other two cases by bilateral neck exploration (BNE). The procedure for 3 cases of parathyroid carcinoma was the same as that for papillary thyroid carcinoma. Unilateral resection of thyroid and parathyroid was done in a case of parathyroidoma with malignant change. Emergency excision of parathyroidoma, after (emergency) medical management, was performed in a patient with parathyroid storm, and the symptoms (subsided) postoperatively. All cases developed hypocalcemia in various degrees after surgery, but the symptoms were relieved with the use of calcium gluconate. Conclusions PHPT could be diagnosed according to (co-elevated) calcemia and PTH. Ultrasonography and ECT should be considered as the methods of first choice for preoperative localization. UNE of parathyroidoma could be feasible if accurate image localizations are (available). Radionuclear guided parathyroid resection could be performed in the patients with ectopic parathyroid disease or lesions without accurate localization. Aggressive surgical exploration after medical control of (symptoms) is the first choice of treatment when parathyroid storm is diagnosed.
