The answer is E.
Thyrotoxicosis factitia is characterized by exogenous of thyroid hormone. Radionuclide scans
show low uptake. Unlike the situation in cases of thyroiditis, serum thyroglobulin levels are low
or normal. Stuma ovarii and ectopic thyroid tissue are identified by evidence of uptake on
whole-body radionuclide scans. Graves' disease is characterized by diffuse thyroid enlargement
and increased uptake on uptake scanning.
