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 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

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
