Study note

Ultrasonography of thyroid nodules

THE CONTEXT

Ultrasonography assesses the physical characteristics of thyroid swellings and is the primary investigation for any thyroid nodule.

•

Microcalcification and increased vascularity are associated with thyroid neoplasia.

•

Only macroscopic capsular breach and nodal involvement are described as diagnostic of malignancy.

•

Use ultrasonography as the primary investigation of any thyroid nodule.

•

A reassuring ultrasonographic appearance mitigates the need for fine-needle aspiration cytology.
