Read about thyroid nodules, lumps in the thyroid gland. Symptoms include a lump in the neck, a lump felt in the throat, difficulty swallowing, hoarseness, or enlarged glands or lymph nodes in the neck. Causes, diagnosis, treatment, and surgery information is included.
Thyroid cysts, also known as thyroid nodules, are small sacs filled with fluid or blood that grow on the thyroid. These sacs can also be filled with solid matter, which is sometimes an indicator of thyroid cancer. The thyroid is an endocrine gland located at the bottom of a person’s throat, at the trachea.
What Are the Causes of Thyroid Cysts? The underlying cause of a growth in thyroid tissue, the source of thyroid nodules, of which a thyroid cyst is a variety, is unknown, explains Cleveland Clinic. However, degenerating thyroid adenomas are the most common cause of thyroid cysts specifically, according to Mayo Clinic.
The probe detects these reflections to make pictures. This nodule (shown in red) comprises about 80% of the thyroid tissue (shown in yellow) in this particular area of the thyroid. If you looked at other parts of the thyroid, however, you would not see the nodulem; you would only see normal thyroid tissue.
Thyroid cyst. Fluid-filled cavities (cysts) in the thyroid most commonly result from degenerating thyroid adenomas. Often, solid components are mixed with fluid in thyroid cysts. Cysts are usually benign, but they occasionally contain malignant solid components. Chronic inflammation of the thyroid (thyroiditis).
Following are treatment options for thyroid cysts: Large cysts, greater than 3 centimeters, that have a solid component should be aspirated. Pure cysts, smaller than 3 centimeters, may be followed with an exam and ultrasound to assess for change. Alternative management includes ablative methods such as the instillation of ethanol.
A cyst, by definition, contains fluid. Thyroid cysts are regions of the thyroid that are enlarged and filled with fluid. They may be small (1 cm) or sometimes very large and can develop slowly or arise suddenly. Thyroid nodules can also degenerate and become fluid-filled sacs entirely or have a combination of solid and cystic areas.
Cysts that are completely fluid filled have a much lower risk of thyroid cancer compared to cysts that have solid components. Diagnosis of a cystic thyroid lesion may be made at the time of ultrasound, or following a fine needle biopsy when fluid is obtained from the thyroid cyst. Spontaneous resolution of a thyroid cyst is rare but may occur ...

Fine needle aspiration is also performed to treat thyroid cysts. The fine needle aspiration biopsy procedure may be recommended to make the diagnosis and/or select therapy of a thyroid nodule. Fine needle aspiration biopsy may also be recommended to drain or shrink a thyroid cyst.
