Abstract

We report a case of post menopausal women who had total thyroidectomy due to papillary thyroid carcinoma and then underwent radioiodine therapy. After radioiodine therapy, total body scan (TBS) was administered and we observed that breast tissıe uptake of radioiodine. The scintigraphic and associated clinical characteristics of radioiodine breast uptake in non-breastfeeding patient with thyroid cancer was an unexpected finding. In this patient, elevated serum prolactin levels were documented at the time when radioiodine uptake in the breast was observed. We conducted a hypophysis MRI and we detected an pituitary adenoma. Medical treatment with cabergoline was given to this patient. When prolactin levels were normalized, breast tissue uptake was no longer evident on TBS.
