Successful treatment by surgical removal of bone metastasis producing PTH: new approach to the management of metastatic parathyroid carcinoma.
A 62-year-old woman had primary hyperparathyroidism due to parathyroid carcinoma. In spite of surgical removal of the enlarged parathyroid gland, intractable hypercalcemia persisted. 99mTc-methoxyisobutylisonitrile scanning revealed bone metastatic lesions, although conventional 201T1-chloride scanning failed to demonstrate those lesions. Octreotide inhibited parathyroid hormone (PTH) secretion, although various means such as bisphosphonates, calcitonin and hydration were effective to reduce serum calcium level to some extent but failed to reduce PTH secretion at all. The CT-guided transcutaneous tumor marking facilitated the subsequent orthopedic surgery for successful removal of the metastatic focus of PTH secretion from the iliac bone.
