Ultrasonography for diagnosis of extrathyroidal extension

(A) The lesion is not in contact with the capsule. According to the classification criteria, the contact angle with the thyroid capsule is 0°. (B) The lesion formed an acute angle with the thyroid capsule. (C) The lesion formed a straight angle with the thyroid capsule. (D) Thyroid capsule deformation for the bulging nodule. (E) The arrow indicates that the CDFI vascularity of suspicious extrathyroidal extension nodules extended beyond the thyroid capsule. (F) The arrows pointing at contrast-enhanced ultrasound imaging showed discontinuous enhancement of the anterior thyroid capsule
