High resolution ultrasound can detect a diagnosis of papillary thyroid cancer spread to lymph nodes as small as 1-2 mm (the size of a tip of a ball point pen). When looking at the lymph nodes in the neck with ultrasound, the following are important criteria which may lead to a FNA needle biopsy to confirm disease.
What thyroid cancer looks like on ultrasound?
A malignant thyroid nodule tends to have ill-defined margins on ultrasound (Fig. 1). A peripheral halo of decreased echogenicity is seen around hypoechoic and isoechoic nodules and is caused by either the capsule of the nodule or compressed thyroid tissue and vessels .

Most patients with thyroid cancer have the cancer contained in the thyroid at the time of diagnosis. About 30% will have metastatic cancer, with most having spread of the cancer to the lymph nodes in the neck and only 1-4% having spread of the cancer outside of the neck to other organs such as the lungs and bone.
What makes a thyroid nodule suspicious?
For the U.S. population, the lifetime risk of developing thyroid cancer is 1.1 percent. When a thyroid nodule is suspicious – meaning that it has characteristics that suggest thyroid cancer – the next step is usually a fine needle aspiration biopsy (FNAB).
