A complex association has been demonstrated between breast cancer and thyroid disease, although the mechanism remains elusive. Development of chronic thyroiditis and\/or goiter in breast cancer patients has been suggested to convey a more favorable prognosis. Goiter extension is almost exclusively into retrosternal space, with only a handful of cases reported with superior extension into retropharyngeal space. We present a rare case of a diffusely enlarged goiter extending superior and posterior into the retropharyngeal space with an associated intense <jats:sup>18<\/jats:sup>F-FDG avidity standardized uptake value maximum (SUV<jats:sub>max<\/jats:sub>) of 16.1 in a patient with invasive ductal breast cancer.
