Abstract

Ultrasonography (US) features of thyroid nodules can be helpful in identifying those most at risk for malignancy; these features include marked hypoechogenicity, microcalcifications, irregular margins, and a taller-than-wide shape (nonparallel orientation). Some cystic nodules change morphologically after simple aspiration and percutaneous ethanol injection treatment. They can show marked hypoechogenicity and irregular margins on the US and be difficult to distinguish from papillary thyroid carcinoma. This article covered the imaging precautions when a malignant nodule is suspected in the US during the clinical course of a thyroid cyst.
