PURPOSE: To assess the use of Tc-99m sestamibi to localize recurrent and metastatic parathyroid carcinoma. METHODS: A patient with a history of parathyroid carcinoma that was resected 6 months before had high serum calcium and high serum parathyroid hormone levels. Tc-99m sestamibi imaging was performed to localize the recurrence. RESULTS: Tc-99 sestamibi imaging detected the recurrence and the metastatic lymph nodes. These findings were confirmed surgically and pathologically. CONCLUSION: Tc-99m sestamibi can be useful in diagnosing and localizing metastatic parathyroid carcinoma.
