BACKGROUND: It is desirable to detect neoplastic thyroid disease before proceeding with surgical therapy for hyperparathyroidism so that both conditions can be treated with a single operation. METHODS: Between March 1998 and June 2009, 227 patients with primary hyperparathyroidism were treated with surgical therapy. Of these, 217 were evaluated preoperatively with a modified 4-dimensional CT and ultrasonography. The medical records of these patients were reviewed in order to document the incidence and significance of thyroid pathology in this cohort of patients. RESULTS: Thyroid nodules were identified in 159 of the 217 patients (73.3%). Nine of 217 patients (4.1%) were treated with either a partial or a total thyroidectomy at the time of parathyroidectomy. Three of these patients had papillary thyroid carcinoma, 1 had a Hurthle cell carcinoma, and 1 had an incidental micropapillary thyroid carcinoma. CONCLUSION: The rate of clinically significant thyroid malignancy in patients undergoing surgical treatment of primary hyperparathyroidism was 1.8%.
