Isoechoic Thyroid Nodule With Hypoechoic Halo, May 24, 2026 · A hypoechoic thyroid nodule appears dark on an ultrasound.

Isoechoic Thyroid Nodule With Hypoechoic Halo, Images from ultrasound exams performed on different patients show (a) a hypoechoic nodule, (b) a hyperechoic nodule, (c) an isoechoic nodule, (d) a heterogeneous solid nodule with both hyperechoic and hypoechoic solid portions, and (e) a mixed cystic and solid nodule in which the solid component is isoechoic to the parenchyma. Ultrasound uses soundwaves to create a picture of the structure of the thyroid gland and accurately identify There are specific characteristics about the nodule that can be seen with an ultrasound machine including: If the lesion is solid, cystic (fluid-filled), or complex (both solid and cystic); hypoechoic, isoechoic, or hyperechoic; and If the lesion shows calcification, halo sign, or irregular shape or vascularity. The presence of a smooth margin or a thin, well-defined hypoechoic halo—a dark rim—also points toward a benign diagnosis. The nodules depicted in (b) and (d) proved to Figure 2. Ultrasound uses soundwaves to create a picture of the structure of the thyroid gland and accurately identify Nov 17, 2025 · Learn how ultrasound echogenicity (isoechoic vs. Read our expert guide.
