US Characteristics of Thyroid Malignancy: Pearls and Pitfalls
Introduction

Thyroid nodules have become common and might certain you're seen at ultrasonography (US) in 50% in the adult population. Thyroid malignancy is fairly rare which is diagnosed in approximately 25,000 patients a year in the us (1). The commonest source of benign thyroid nodules is nodular hyperplasia (2). Although below 7% of thyroid nodules are malignant (2), it is essential that they can be accurately identified. The imaging modality preferred by the analysis of thyroid nodules is high-resolution US. US is frequently misperceived as unhelpful in distinguishing between benign and malignant thyroid nodules. Although individual US features could possibly be of limited value, when multiple warning signs of thyroid malignancy show up in combination you are able to make a definative prediction. The nodule then could possibly be further assessed with fine-needle aspiration (FNA).

Scintigraphy just sits there routinely to gauge thyroid nodules. It can be primarily people in patients which has a suppressed thyroid-stimulating hormone level, in whom it enables assessment in the functional activity of an thyroid nodule in addition to the full gland. A functioning, or “hot,” thyroid nodule has never been malignant, with a number of reported installments of such malignancy (3-10). Although a nonfunctioning, or “cold,” nodule at scintigraphy is frequently shown to indicate a greater probability of thyroid malignancy, possibly 77% of cold thyroid nodules could possibly be benign (4,11). Thyroid scintigraphy therefore is unhelpful for differentiating a benign nodule coming from a malignant one, as well as utility to the routine evaluation of thyroid nodules is bound.
