Thyroid hyperechoic peripheral blood flow surround signal, may be thyroid nodules caused by thyroiditis, belong to the substantial nodule, but does not exclude the thyroid malignant tumor, so to assess whether it is a malignant manifestation. If the thyroid nodule, peripheral blood flow signal is not abundant, there is no coarse calcification, the border is relatively clear, the morphology is relatively regular, and the mobility is good, this case is mostly a benign thyroid nodule manifestation. If there is abundant blood flow in the parenchyma of the thyroid nodule, the border is not clear, the aspect ratio is greater than 1 cm, and there is sand-like calcification inside, it is very likely to be a malignant thyroid nodule, and it is necessary to do pathological examination by puncture in order to confirm the diagnosis. If the patient has thyroid hyperechoic surrounded by blood flow signal, it is recommended to consult a doctor in time, under the guidance of the doctor, to clarify the cause of the disease, and take the appropriate treatment plan.
