It is not possible to determine the benign or malignant nature of a nodule by relying only on thyroid punctate strong echoes. It may be caused by calcification of the thyroid nodule and malignant thyroid nodules. The three main categories of punctate strong echoes in thyroid ultrasonography include microcalcifications, comet tail pseudo-images, and unclear significance. Microcalcification refers to 1~2mm punctate strong echoes in ultrasound without posterior acoustic shadowing, which corresponds to gravel bodies in pathology, suggesting the possible presence of papillary thyroid carcinoma, which is a suspicious sign of malignancy. The comet tail artifact refers to the point-like echoes with ringing or reverberation artifacts behind the acoustic shadow, which corresponds to the pathology of condensed colloid calcification and is a benign sign. Some punctate echoes are difficult to categorize as benign or suspected of being malignant and are of uncertain significance. Patients are advised to check the additional description of punctate echoes in the ultrasound report and the specific description of the echoes, and to follow the TIRADS classification for further investigation and treatment under the guidance of their physician.
