How to treat cystic nodules in both lobes of the thyroid requires a comprehensive analysis based on the size of the nodule and the nature of the nodule. The most common disease of bilobar cystic nodules in the thyroid is nodular goiter, which is benign but may grow larger or extend into the posterior sternum.
If the nodular goiter is large and compresses the trachea, esophagus, or blood vessels or nerves in the neck, causing discomfort such as breathlessness, hoarseness, swallowing discomfort, chest tightness, or shortness of breath, or if it affects the aesthetics, surgery may be considered, which requires removal of the goiter or lobectomy.
If the nodule is small and the patient is not in any discomfort, you can consider annual review of the thyroid ultrasound for observation. The nodules are not well-defined, irregular in shape, with internal gravel-like calcifications, abundant blood flow, and a longitudinal ratio greater than 1. For those who cannot be clearly diagnosed on ultrasonography, fine needle aspiration biopsy can be considered to clarify the nature.
In addition, cystic nodules can also provoke hyperthyroidism or hypothyroidism, which requires further thyroid workup and appropriate medication. Therefore, the treatment of cystic nodules in both lobes of the thyroid depends on the size and nature of the nodule and the function of the thyroid gland.
