Common to B ultrasonography: thyroid nodules with calcification
In general, benign thyroid disease appears less calcification, often located in the edge, due to the formation of inflammation and hematoma absorption machine after wall calcification or fibrous septum with nodule calcification; thyroid malignant tumor calcification in the center, because cancer cells grow rapidly, tumor blood vessels and fiber group Zhi Zengsheng, calcium salt deposition, leading to calcification. It is generally believed that micro calcification is the most specific index of thyroid carcinoma.
The incidence of calcification in thyroid benign lesions is about 6%~14%, and most of them are coarse calcification. The total calcification rate of thyroid cancer was 37% to 75.7%, and the incidence rate of microcalcification was from 55% to 68%.
Calcification shadow features and cancer classification may have the following: 1) the relationship between calcification of thyroid malignant tumor is almost there is often features of papillary carcinoma. 2) there are about 10% to 20% of the gross calcification images, and the proportion of follicular thyroid carcinoma is large. 3) medullary carcinoma coarse calcification and often mixed. 4 generally benign thyroid tumor calcification images are mostly coarse calcification, clear edge. Malignant tumors are pale and obscure.
Therefore, if the thyroid nodules with calcification found in the medical examination, you need to find a doctor in a timely manner to the hospital. Especially for micro calcification, but can not let down, to be alert to possible malignant thyroid tumor.
