If this were a simple cyst filled with serous fluid, then it would have no red (artery) or blue (vein) blood flow. This patient had no other nodules in her thyroid, so this was diagnosed as a "dominant complex nodule of the right thyroid lobe."
Thyroid nodules can be solid if they are comprised of thyroid or other cells or an accumulation of stored thyroid hormone called colloid. When nodules contain fluid, they are called cystic nodules. These can be completely fluid filled (simple cysts), or partly solid and partly fluid, (complex cysts). Thyroid nodules vary greatly in size.
The complex cyst larger then 1 cm is subject to FNA, because the higher malignancy risk is associated with large complex cysts. The TSH testing alone is not satisfactory for thyroid condition evaluation; it must be done in the morning before the breakfast; in addition T4 as well as TPO and TG antibodies levels must be obtained.
Complex cysts, like any other thyroid nodules, should be evaluated by experts in ultrasound and thyroid cytopathology when criteria for biopsy or sampling of cells is indicated. Cystic nodules can remain stable, occasionally get smaller and sometime continue to expand. Some cysts may rapidly expand due to bleeding or hemorrhage within the cyst.
Thyroid nodules have a high prevalence among general people with palpable lumps arising in around 4-7% of the population. Read on to find out all about the causes, symptoms, diagnosis and treatment of these abnormal lesions.
A thyroid nodule is a lump in or on the thyroid gland. Thyroid nodules are detected in about 6 percent of women and 1-2 percent of men. Any time a lump is discovered in thyroid tissue, the possibility of cancer must be considered, but more than 95 percent of thyroid nodules are benign.
When the thyroid nodule or cyst is malignant. If the thyroid nodule or cyst is malignant, then there is a high probability it will need to be removed through surgery. Frequently they will remove not only the thyroid nodule or cyst itself, but will perform a partial or complete thyroidectomy. 2. When the nodule or cyst is causing an obstruction.
Some thyroid adenomas (autonomous or hyperfunctioning thyroid nodules) produce thyroid hormones outside of your pituitary gland's normal regulatory influence, leading to an overproduction of thyroid hormones (hyperthyroidism). Thyroid cyst. Fluid-filled cavities (cysts) in the thyroid most commonly result from degenerating thyroid adenomas.
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.
Treating thyroid cysts largely depends on a few very important factors: Is the thyroid cyst "simple" (3) on ultrasound imaging? (small cysts less than 3cm in size can usually be monitored) Is the thyroid cyst "complex" (4) on ultrasound imaging? (Complex cysts usually require a biopsy or needle aspiration to rule out cancer)
