Abstract: Thyroid tumors include adenomas, goiter, and inflammation of the thyroid (thyroiditis), which are the most critical risk factors for thyroid cancer. Adenomas have the most significant increase in risk particularly. The study's objective is to discuss bone metastases in patients diagnosed with adenomas thyroid during follow-ups which are detected by bone scintigraphy. Two patients were referred to the Nuclear Medicine division of Dr. M. Djamil Hospital in Padang-Indonesia for bone scintigraphy examination. Both patients had thyroid surgery histories. The histopathology results were adenomas. However, after the removal surgery, the patients did not have proper follow-ups. Both patients developed pelvic pain. Bone scintigraphy results showed increased uptake at pelvic bones, and computerized tomography (CT Scan) showed destruction. Conclusions: These cases highlight the necessity for adenoma thyroid patients with a risk factor for thyroid cancer to have a complete follow-up program with a sufficient length period. Bone scintigraphy can be used as a tool to detect bone metastases in thyroid tumor diseases.
