Cystic nodules in the bilateral lobes of the thyroid gland are not serious and should not be overly stressed. The incidence of cystic thyroid lesions is very high, especially in middle-aged women, with significant regional differences. If there is significant pain, surgical treatment may also be an option. And it needs to be further combined with thyroid function measurements, because multiple lesions with a long history of disease are also prone to secondary hyperthyroidism. Postoperatively, it is also important to monitor the changes in thyroid function and supplement with small doses of thyroxine tablets if necessary.
