It means it contain some fluid(colloid) as well as some solid material(could be fibrous tissue).
Full Definition of NODULE. : a small mass of rounded or irregular shape: as a: a small rounded lump of a mineral or mineral aggregate b: a swelling on a leguminous root that contains symbiotic bacteria c: a small abnormal knobby bodily protuberance (as a tumorous growth or a calcification near an arthritic joint). Definition. Thyroid nodules are solid or fluid-filled lumps that form within your thyroid, a small gland located at the base of your neck, just above your breastbone. The great majority of thyroid nodules aren't serious and don't cause symptoms. Thyroid cancer accounts for only a small percentage of thyroid nodules To evaluate the frequency of malignancy in mixed echoic thyroid nodules and ascertain the ultrasound findings that help distinguish benign from malignant nodules.  Several conditions can cause nodules to develop in your thyroid gland: 1  Iodine deficiency. 2  Lack of iodine in your diet can sometimes cause your thyroid gland to develop thyroid nodules. 3  But iodine deficiency is uncommon in the United States, where iodine is routinely added to table salt and other foods. 1 Goiter is a term used to describe any enlargement of the thyroid gland, which can be caused by iodine deficiency or a thyroid disorder. 2  A multinodular goiter contains multiple distinct nodules within the goiter, but its cause is less clear. 3  Thyroid cancer. Some goiters are diffuse, meaning that the whole gland is large. Other goiters are nodular, meaning that the gland is large and has one or more nodules (bumps) in it. There are many reasons the thyroid gland might be larger than usual, and most of the time it is not cancer. These nodules are more likely to be cancerous than are fluid-filled nodules. Still, most solid nodules are not cancer. Some types of solid nodules, such as hyperplastic nodules and adenomas, have too many cells, but the cells are not cancer cells. A thyroid nodule is a lump in or on the thyroid gland. Thyroid nodules are common and detected in about six percent of women and one to two percent of men; they are less common in younger patients and occur 10 times as often in older individuals, but are usually not diagnosed. Sometimes several nodules will develop in the same person. Any time a lump is discovered in thyroid tissue, the possibility of malignancy (cancer) must be considered. More than 95 percent of thyroid nodules are benign (non-cancerous), but tests are needed to determine if a nodule is cancerous. Malignancy rate of ground-glass nodules at baseline CT. Compared to a malignancy rate of 4.6% for all solid nodules, nodular GGO (nGGO) had a higher malignancy rate of 5.4%, pure nodular GGO (pnGGO) had a malignancy rate of 3.3%, and mixed nodular GGO (mnGGO) had a malignancy rate of 14.3%. 1 Often, solid components are mixed with fluid in thyroid cysts. 2  Cysts are usually benign, but they occasionally contain malignant solid components. 3  Chronic inflammation of the thyroid (thyroiditis). 4  Hashimoto's disease, a thyroid disorder, can cause thyroid inflammation resulting in nodular enlargement. 1 Goiter is a term used to describe any enlargement of the thyroid gland, which can be caused by iodine deficiency or a thyroid disorder. 2  A multinodular goiter contains multiple distinct nodules within the goiter, but its cause is less clear. 3  Thyroid cancer. show more I had a thyroid ultrasound..results are slightly enlarged gland. 4 nodules total, 3 are solid 1 is mixed...2 on right side one is consistnent with fibroadenoma the lower pole mass is indeterminate due to mixed echogenicity..... The fibroadenoma is actually the term describing the benign (NON-CANCEROUS) tumor in the breast; I never saw this term in description of thyroid ultrasound result. The mass of mixed echogenicity means the tissue it composed from is not uniform, but is not meaning it is cancerous. The mixed nodule means it contain some fluid (colloid) as well as some solid material (could be fibrous tissue). More then one nodule in many cases means the nodules are benign (not cancerous) The biopsy (FNA) is in many cases performed if nodule is greater then 1 cm in size
