In brief: Fewer echoes on US
Hypoechoic describes the appearance of a nodule on ultrasound (us).
It refers to a nodule that reflects back fewer sound waves compared to the normal thyroid tissue around it. While most thyroid cancers are hypoechoic, most hypoechoic nodules are not cancers. But a hypoechoic nodule may have a slightly higher risk of being a cancer than other nodules.

In brief: Dark on ultrasound
A hypoechoic thyroid nodule is a nodule that appears darker than normal surrounding thyroid tissue.
This occurs because the tissue in the nodule does not reflect as many sound waves as the surrounding tissue. In general, hypoechoic thyroid nodules are considered more supicious for harboring a cancer. Your doctor will need to determine if there are other characteristics that warrant biopsy.
