Multiple follicular cysts of the thyroid gland with normal thyroid function are usually benign lesions. If a follicular cyst is unusually large and produces pressure, it may require surgical intervention under the supervision of a doctor. The vast majority of thyroid cysts are benign. A specialized ultrasonographer is required to determine whether a follicular cyst is benign or malignant based on a number of factors, including its shape, borders, and whether it is calcified, but the gold standard is to obtain pathological tissue to determine the benign or malignant nature of the cyst. If the multiple follicular cysts of the thyroid gland show symptoms of compressing the local trachea, or compressing the esophagus and causing difficulty in swallowing, surgical resection is needed; otherwise, they can be observed regularly. Therefore, the next step in the management and treatment of thyroid follicular cysts found on examination should be decided by a specialized glandular surgeon.
