The classic appearance of the thyroid in patients with lymphocytic thyroiditis, also known as Hashimoto's thyroiditis, is that of a diffusely abnormal gland that may be heterogeneous and hypoechoic [1,2,3] or that may show a fine micronodular pattern [4, 5].Rather than a diffuse process, thyroiditis may also present as a focal, often palpable abnormality simulating nodular disease [6,7,8].
