Intrathyroidal thymic tissue is a rare ultrasound finding and may be confused with a malignant thyroid nodule because of hyperechoic dots mimicking calcifications. We retrospectively evaluated thyroidultrasound examinations of a paediatric population consisting of 205 children. Ten patients showedthyroid nodules with hyperechoic foci like those seen in thymic tissue. The knowledge and awarenessof intrathyroidal ectopic thymus and its ultrasound features allows to avoid misdiagnosis of thyroid malignant nodules.
