Fig. 1. —37-year-old-woman with 3-cm left-sided nodule that proved to be papillary thyroid carcinoma. Sagittal sonogram of right lobe obtained at time of diagnosis of left-sided thyroid carcinoma shows 11-mm hypoechoic solid nodule with ill-defined margins (delineated by electronic calipers) in upper pole of right lobe. Sonographically guided fine-needle aspiration of this nodule and surgical pathology findings were consistent with lymphocytic thyroiditis. Remainder of thyroid has hypoechoic micronodules (arrows), a pattern that has a high positive predictive value for antibody-positive lymphocytic thyroiditis [4, 5].
