Excerpt
Thyroid nodules are common in the adult population. Ultrasonographic features of the nodules are known predictors of the risk of malignancy and are used for the indication of fine-needle aspiration (FNA). Recently, the American Thyroid Association (ATA) proposed a classification of thyroid nodules into five categories based on these features [
1]. In the “benign” category, diagnostic FNA is not recommended [
1]. It is also acceptable not to perform FNA in the “very low suspicion” category [
1]. Solid nodules for which greater concern for malignancy exists are classified into three other categories (“low suspicion”, “intermediate suspicion”, and “high suspicion”) [
1]. …
