We report a 37 year-old-female patient with papillary thyroid cancer treated by surgery who demonstrated residual thyroid and bilateral breast uptake on a diagnostic I-131 whole body scan. She had an extrathyroidal extension needing I-131 ablative therapy. Her galactorrhea was investigated and treated with low doses of bromocriptine prior to I-131 therapy. Her galactorrhea was due to the decreased secretion of PIF induced by empty sella.
