Incidental thyroid Tc-99m methylene diphosphonate (MDP) uptake in a patient affected by polynodular goiter at bone scintigraphy

Abstract

Incidental extraosseous uptake seen on Tc-99m methylene diphosphonate (MDP) bone scan is not unusual. We discuss here an incidental thyroid uptake in a 55-year-old female patient affected by breast cancer treated by total mastectomy, who underwent total body bone scintigraphy as a staging study. In the positron emission tomography era, traditional nuclear medicine imaging still has an important role in the diagnostic field, and incidental findings may be very useful in patient management, revealing unknown diseases and allowing correct therapeutic decisions
