Multiple benign-cysts and -nodules are detected. (B) At age 10 years and 9 months, during the Graves’ disease period, sonography showed a diffuse goiter and increased vascularity. (C) At age 12 years and 2 months, sonography shows goiter and heterogenous echotexture consistent with Graves’ disease.
