A few Facts about Thyroid CystsThyroid cysts are the enlarged fluid-filled regions of the thyroid. Thyroid cysts are actually just like water balloons (without the tied knot on the outside). These thyroid cysts are like sacs filled with liquid, and only liquid and are virtually always benign. These may be small (even less than 1 cm) or quite large and sometimes appear very suddenly. Thyroid nodules may be entirely cystic, in which case there are no solid components detectable within the fluid. Alternatively, it may also contain both fluid and solid components. Cystic nodules may expand and enlarge suddenly sometimes due to hemorrhage or bleeding within a smaller pre-existing nodule. In some cases, rapidly enlarging cysts may produce symptoms in the neck, including pain, trouble swallowing, and rarely, compression of vocal cords leading to hoarseness of voice. Cysts that are entirely fluid filled have a much lower risk of harboring a small thyroid cancer compared to cysts that have solid components. Although the thyroid cysts do not interfere with the hormone production and have no significance, they tend to recur, causing a lot of discomfort to the patient. It would be wise to get an ultrasound exam of the thyroid done as it is useful in looking for thyroid masses, which could be more significant. Another test may also be performed,when fluid is drained from the cyst using a fine needle and used for cellular analysis,to check for cancerous growth.
