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]
Ultrasound characteristics of thyroid nodules
▸ Halo sign or a smooth magrin
▸ Normal reactive cervical nodes
▸ Cystic nodule
▸ Spongioform nodules
▸ Hyperechoic masses
▸ Eggshell calcifications
▸ A decrease in size over time
Adapted from Arzu Tatlıpınar1 and İlkay Kartal [Updated 2015].The Evaluation of Thyroid Nodules. Journal of Thyroid Disorders & Therapy.2015.[2]

Colloid Nodule

  • Isoechoic to hypoechoic
  • May have internal cystic or heterogeneous change
  • May have calcification
  • Multiple echogenic foci (of inspissated colloid) with comet tail artifact
