Thyroid cartilage metastases on F-18 Fluorodeoxyglucose positron emission tomography-computed tomography: A tale of two cases with a brief review of literature

Abstract

Metastases to thyroid cartilage are rare entities and can often easily be missed on computed tomography (CT) scan alone. Positron emission tomography (PET)-CT imaging has overcome this diagnostic dilemma due to its ability to provide for both anatomical and functional imaging. We report two rare cases of thyroid cartilage metastases on F-18 fluorodeoxyglucose PET-CT from breast and papillary thyroid malignancies as primaries.
