Thyroid cysts with thin walls and punctate echoes may be calcification, which should be evaluated together with other ultrasound findings, and if necessary, puncture biopsy should be performed to determine the benign or malignant nature of the cysts; benign cysts without clinical symptoms do not require treatment, while malignant cysts with obvious symptoms can be treated with surgery. Thyroid cysts with thin walls and punctate echoes usually suggest punctate calcification, which should be evaluated in conjunction with other ultrasound findings to determine the benign or malignant nature of the cyst. If the benign cyst is small, the patient does not have any clinical symptoms, and the cyst does not grow or grows slowly, it is usually recommended to review the cyst regularly and observe the lesion closely. If the thyroid cyst is relatively large and the cyst is compressing the surrounding organs, the patient will experience symptoms such as breath-holding and choking sensation when eating, or if the cyst is suspected to be malignant, surgery is recommended. Patients are advised to go to a regular medical institution and need to complete the examination to determine the severity of the condition before deciding how to treat it.
