If the cystic thyroid adenoma is small and there are no obvious symptoms of compression, it can be considered for follow-up observation, but if it is large and compresses the surrounding organs, it can be considered for treatment. The main treatments for thyroid cystadenoma are antithyroid medication, radionuclide iodine therapy, surgery, and interventional embolization. At present, the less invasive method is aspiration by puncture, where the location of the cystic adenoma is accurately located under ultrasound guidance and the internal fluid is extracted with a puncture needle to shrink the cystic adenoma.
