Ultrasonography of the neck and thyroid can be used to detect nodules and infiltrative disease. It has little use in hypothyroidism per se unless a secondary anatomic lesion in the gland is of clinical concern. Hashimoto thyroiditis is usually associated with a diffusely heterogeneous ultrasonographic image. In rare cases, it may be associated with lymphoma of the thyroid. Serial images with fine-needle aspiration (FNA) of suspicious nodules may be useful.
