Sonographic and Elastographic Features of Extra- and Intrathyroidal Ectopic Thymus Mimicking Malignancy: Differential Diagnosis in Children
In conclusion, despite the low prevalence of IET and cervical EET, clinicians and radiologists should be aware of US characteristics of such lesions and of the necessity of confirmation of their benign character. Elastography is a useful tool to initially differentiate PTC and IET. However, due to the high risk of malignancy in thyroid lesions in children, similarity of US features of PTC and IET, and because of the possibility of malignancy in ET, only cytological evaluation provides definitive diagnosis and prevents, on one hand, unnecessary frequent diagnostic procedures and/or surgery and, on the other hand, missing malignant lesions.
