except this is about Hashimoto's thyroiditis, in which micronodules are a feature.

Don't know if this helps, but the French Endocrinology Society guidelines for ultrasound evaluation of thyroid nodules :

"A nodule can be solid, cystic
(fluid-filled) or mixed. In the latter case, it is advisable to indicate
what the predominant component is and in what proportion.
The characterisation of mixed nodules is done based on the
echogenicity of the solid portion.
Thick fluid-filled nodules (colloid, blood, etc.) may falsely
take on a solid hypoechoic appearance. Doppler and elastography
are then very useful, as a cystic nodule has no vascularity.
Its elastographic appearance is characteristic (very contrasted
bizone image).
The cystic nodule is defined by four characteristics in B-mode
ultrasound:
• anechoic at the normal gain setting;
• filling up with fine echos in gain saturation;
• without its own wall or with a fine and regular wall;
• with posterior reinforcement."

I think in the second instance , I would translate as 'not mixed'.
