Overview
On ultrasound, thyroid adenoma is characterized by halo sign or smooth margin of thyroid, hyperechoic nodules, and normal reactive cervical nodes.
Ultrasound
Key Ultrasound Findings in Thyroid Adenoma
- The blood assays may be accompanied by ultrasound imaging of the nodule to determine the position, size, and texture, and to assess whether the nodule may be cystic (fluid filled).
- Ultrasound features showing a significant association with malignancy:[1]
- Solid component
- Hypoechogenicity
- Marked hypoechogenicity
- Microlobulated or irregular margins
- Microcalcifications
- Taller-than-wide shape
- Risk of malignancy increases with the increase in number of suspicious ultrasound features.[1]
