There is a benign possibility of nodular echogenic calcification of the thyroid gland. Thyroid nodular echogenicity can be categorized into intraglandular echogenicity and intraglandular nodular echogenicity. 1. Intra-glandular strong echoes: If the strong echogenic spot in the thyroid gland is usually not caused by cancer, it is mostly benign calcified foci, and it will be manifested as a neck mass with smooth surface, clear boundary, and intact peritoneum. It may be related to local tissue degeneration and vascular obstruction, and requires regular review. 2. Strong echoes of nodules in the gland: the presence of strong echoes in thyroid nodules suggests that calcification of the nodules may occur. If there is a strong echogenic spot in the gland with a comet tail, most of them are multiple nodules and are benign. If the nodule is purely punctate strong echoes without a comet tail, it may be a single isolated nodule without an envelope, which is considered to be more likely to be malignant. If the thyroid nodular echogenic calcification, it is recommended to go to the hospital in time, do the relevant examination to clarify the cause of the disease, and actively treat it under the guidance of the doctor, so as not to delay the condition.
