Roentgenographic-Histologic Patterns of Calcification in Thyroid Nodules

The calcifications occurring in thyroid nodules present a great variety of forms on roentgenograms of the neck. Thus far several investigators have attempted to formulate the criteria by which differentiation of benign and malignant nodules may be roentgenologically possible. It has been generally agreed that, when calcium deposits in the thyroid nodules are grossly classified into two types, “psammomatous” and “coarse”, the former has diagnostic value because of its occurrence almost exclusively in cases of thyroid carcinoma, whereas the latter bears no relationship to the histologic diagnosis.
