Ultrasound. This imaging technique uses high-frequency sound waves to produce images of your thyroid gland. A thyroid ultrasound provides the best information about the shape and structure of nodules. Doctors may use it to distinguish cysts from solid nodules or to determine if multiple nodules are present.
Ultrasound Characteristics That Suggest a Benign Nodule. Sharp edges are seen all around the nodule; Nodule filled with fluid and not live tissue (a cyst) Lots of nodules throughout the thyroid (almost always a benign multi-nodular goiter) No blood flowing through it (not live tissue, likely a cyst) More on this topic on our FNA page
Ultrasound is the first line imaging modality for assessment of thyroid nodules found on clinical examination or incidentally on another imaging modality. This article is an overview on ultrasonographic features of thyroid nodules, which are used to determine the need for biopsy with fine needle aspiration.Specific management guidelines from various professional societies are covered in ...
Thyroid nodules that are complex in nature contain both solid and fluid components. Thyroid nodules are usually caused by thyroiditis, iodine deficiency, thyroid adenoma, thyroid cyst, and thyroid cancer . Some facts regarding thyroid nodules include: Thyroid nodule is detected in thirty percent of thirty-year-old women
Most large cysts or complex cysts should be aspirated with a fine needle to rule out the possibility of malignancy. Ultrasound-guided needle biopsies of a complex cystic nodule is necessary to insure that the biopsy material contains thyroid cells, and not just cystic fluid.
Thyroid nodules can be detected in 4% to 8% of the adult population by palpation, but in 40% to 50% of the population by ultrasound. The overwhelming majority of these represent benign hyperplastic nodules or adenomas. Approximately 5% of nodules are malignant, with papillary carcinoma representing approximately 75% to 80% of primary thyroid malignancies.
Thyroid cysts most often remain asymptomatic and are detected during an imaging process such as ultrasonography or computerized tomography, performed on the neck area for irrelevant reasons. This is why thyroid nodules are often termed "thyroid incidentalomas" (discovered incidentally) .. In some cases, nodules produce symptomatology due to spontaneous hemorrhage of smaller or bigger ...
Most thyroid nodules are benign and nothing to worry about but some (about 5-10%) may be cancerous. ... Thyroid cysts - Thyroid cysts are a type of thyroid nodule but they are filled with fluid. These cysts are often identified very easily with thyroid ultrasound but can present the same way as a thyroid nodule. ... don't want to get a biopsy ...

INTRODUCTION. Thyroid nodules are common, and a large proportion has mixed cystic and solid components. In some studies, a nodule is called a cyst only if it is predominantly cystic on ultrasonography, but in others the term is applied to nodules that are predominantly solid but have small areas of cystic degeneration.
