What is a well defined nodule?
A solitary pulmonary nodule or “spot on the lung” is defined as a discrete, well-defined, rounded opacity less than or equal to 3 cm (1.5 inches) in diameter that is completely surrounded by lung tissue, does not touch the root of the lung or mediastinum, and is not associated with enlarged lymph nodes, collapsed lung.

Tumors that are generally larger than three centimeters (1.2 inches) are called masses. If your tumor is three centimeters or less in diameter, it’s commonly called a nodule. If the nodule forms in your lungs, it’s called a pulmonary nodule. Hamartomas are the most common type of benign lung nodule.

The echogenicity refers to the brightness of a thyroid nodule relative to the rest of the thyroid tissue. Hypoechoic nodules are darker than the surrounding thyroid tissue, which suggests that the nodules are solid rather than fluid-filled.
What does a hypoechoic mass look like on an ultrasound?
Some of the features that show as a hypoechoic mass on ultrasound that are indicative of a malignant breast mass include: or a duct extension. and spiculation, which probably has the highest positive predictive value for malignant breast cancer.

How big is a thyroid nodule on ultrasound?
“subtle solid-appearing nodule at the midpoint measuring 6 x 5 x 6 mm, ill defined.

Appropriate follow-up advised as clinically indicated.”
What does it mean when a nodule looks dark on an ultrasound?
Things that absorb sound and don’t bounce echos back to the scanning probe, are DARK on the ultrasound images. Hyper means a lot of echos, made something look bright, and hypo -echoic means the nodule looks dark on the ultrasound. Bright is good, dark is bad, usually.
