Increased pertechnetate and radioiodine uptake in the thyroid gland with subacute thyroiditis and concurrent Graves' disease.

CONCLUSION: This case indicated that the measurement of TSHRAb is useful in understanding the clinical course of patients with SAT when thyroid function tests including the (99m)Tc and (131)I uptake are not compatible with the diagnosis. In such cases, GD should be suspected. The mechanism of high (99m)Tc and/or (131)I uptake in patients with simultaneous SAT and GD may be due to the inflammatory process which was detected by FNA in a small part of the left thyroid lobe inducing the stimulating effects of elevated TSHRAb on the undamaged follicular cells.
