Hyperthyroidism-induced thyrotoxicosis the reasons for the differential

GD, toxic nodular goiter and autonomous high-functioning thyroid adenoma causes each accounted for about 80%, 10% and 5%. Exophthalmos with infiltration, and TSAb TRAh positive, anterior tibial myxedema and so support the GD diagnosis. Not typical GD should be excluded toxic nodular goiter, thyroid adenoma high-functional autonomy. Identification is the primary means of thyroid radionuclide scan and B-thyroid: GD radionuclides that radionuclide scanning of the distribution of heterogeneous enhanced toxic nodular goiter, that uneven distribution of radionuclide, was strengthening and weakening District kitchen-distribution function of the thyroid adenoma high autonomy only in the tumor area radionuclide increased radionuclide distribution in other regions of the sparse. B-thyroid can be found thyroid adenoma independent high-functional envelope.
