case_images: 68-year-old female with newly diagnosed breast cancer found to have markedly enlarged fluorodeoxyglucose avid goiter with retropharyngeal extension. (a) Fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography coronal reformatted images of the neck and mediastinum including noncontrast computed tomography, fluorine-18-fluorodeoxyglucose positron emission tomography, and fused images demonstrate enlarged bilobar goiter with diffuse fluorodeoxyglucose avidity (white circles). (b) Fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography sagittal reformatted images of the neck including noncontrast computed tomography, fluorine-18-fluorodeoxyglucose positron emission tomography, and fused images demonstrate superior extension of the goiter into the retropharyngeal and prevertebral space (white circles).

case_images: In addition, a diffusely 18F-FDG avid goiter was present (SUVma x 16.1) with superior extension into the retropharyngeal and prevertebral space [Figures 1-3].
case_images: 68-year-old female with newly diagnosed breast cancer found to have markedly enlarged fluorodeoxyglucose avid goiter. Serial fused computed tomography/fluorine-18-fluorodeoxyglucose positron emission tomography coronal reformatted images of the neck from fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography scan demonstrate diffusely intense fluorine-18-fluorodeoxyglucose avidity throughout the bilobar goiter, SUVma x 16.1 (white circles).

case_images: 68-year-old female with newly diagnosed breast cancer found to have markedly enlarged bilobed goiter with retropharyngeal extension. Coronal noncontrast enhanced computed tomography with coned down view of the neck shows bilobar thyroid gland enlargement resulting in mild leftward tracheal deviation (white circle).
