A 30-year-old woman with HT and BMN in the left lobe of the thyroid. A calcification with hyperecho intensity is avoided during the measurement. The ultrasound longitudinal image shows that UGSR is 0.88 (53.38/60.95). B the pathological image (H&E × 40 magnification) demonstrates the presence of accompanied with nodular goiter. The right part of the image corresponds to the nodular goiter, in which high amount of lymphocyte infiltration (yellow arrows) and lymphoid follicles formation (white stars) are observed. The lesion is separated from the surrounding tissues by relatively thick fibers, which are infiltrated with moderate amount of lymphocytes (black stars). Deep infiltration of the fibers is noted in the lesion, which is surrounded with high amount of lymphocyte infiltration (black arrows)
