What is a lobulated heterogeneous hypoechoic nodule with scattered calicifications in the inferior right lobe of thyroid mean?

Thyroid Nodule: Thyroid nodules are very common. About 70% of the population has a nodule (many don't know it). About 5% of nodules are cancerous, which is why we care. Unless there were concerning characteristics on the ultrasound like microcalcifications, >1cm, taller than wide or increased blood flow or you have a family history or radiation exposure, typically we just follow-up with an annual ultrasound.
