Abstract
Herein, we report imaging findings related to an ectopic focus of thyroid tissue in a young female with Graves’ disease. The occurrence of ectopic thyroid tissue affects approximately 7% of adult population and represents commonly an occasional finding. Only rarely ectopic tissue can present with metastasis or develop a primary thyroid carcinoma. Multimodality imaging may be of help in this case to detect thyroid ectopia, although recent studies question its capability to differentiate benign from malignant tissue.
